   **Impact Start Time \(UTC\) 07/23/2026 07:31 AM UTC** **Impact End Time \(UTC\) 07/23/2026 01:01 PM UTC** **Incident Summary** Updated on 08/04/2026 - On 07/23/2026, some NiCE CXone Mpower customers reported experiencing page formatting failures and API call errors within the CXone Mpower Expert service. The incident was caused by incorrect Web Application Firewall \(WAF\) control rules that were deployed as part of a scheduled software release. The issue was resolved after the Engineering team reverted the incorrect WAF rules that had been implemented across the affected regions, restoring normal service operation. **Root Cause** The incident was caused by incorrect WAF control rules that were deployed as part of a scheduled software release. These rules classified and blocked legitimate web and Application Programming Interface \(API\) requests as bot traffic, resulting in service degradation and errors for affected customers. Although a corrective configuration had been identified and merged during pre-deployment validation activities, a build pipeline checkout failure prevented the corrected configuration from being included in the deployed release. As a result, the unintended WAF configuration remained active, causing legitimate customer traffic to be blocked. **Corrective Actions** * **Detection:** NiCE Internal support teams received reports from customers experiencing page formatting failures and API call errors within the CXone Mpower Expert service. * **Remediation:** The issue was resolved after the Engineering team reverted the incorrect WAF rules that had been implemented across the affected regions, restoring normal service operation. Completed on 07/23/2026. * **Prevention:** The Engineering team has updated the build pipeline configuration to address the checkout failure and improve build reliability. Completed on 07/30/2026. The Engineering team has strengthened release deployment criteria by implementing stricter release guidelines to ensure all required builds are available and verified before deployment. Completed on 08/03/2026. The Engineering team is evaluating monitoring and alerting enhancement opportunities to improve visibility and enable earlier detection. An update will be provided by End of Day MT on 08/14/2026. **Incident Timeline \(UTC\)** **07/23/2026 07:31 AM \(UTC\)** - The first customer case was opened, and Tech Support Engineers \(TSEs\) began their initial validations and troubleshooting investigation. **07/23/2026 11:37 AM \(UTC\)** - TSEs notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. **07/23/2026 12:31 PM \(UTC\)** - Engineers identified a suspected cause and began remediation steps. **07/23/2026 01:01 PM \(UTC\)** - The issue was resolved after the Engineering team reverted the incorrect WAF rules that had been implemented across the affected regions, restoring normal service operation.

   **Impact Start Time \(UTC\) 07/01/2026 07:55 AM UTC** **Impact End Time \(UTC\) 07/01/2026 01:21 PM UTC** **Incident Summary:** On 07/01/2026, some NiCE CXone Mpower customers reported service degradation while accessing and using the CXone Mpower Expert knowledge portal. The recurring service degradation was caused by a Domain Name System \(DNS\) resolution bottleneck within the platform infrastructure during periods of elevated traffic. The impact was mitigated after engineers scaled up resources and implemented a node local DNS cache. Service stability was further improved as traffic volumes decreased, allowing the platform to recover and return to normal operation. ## Root Cause The recurring service degradation was caused by a DNS resolution bottleneck within the platform infrastructure during periods of elevated traffic. Increased DNS request volume exceeded infrastructure processing limits, resulting in intermittent DNS lookup failure. These failures triggered application retries, increased latency, elevated “5xx” errors, and customer-facing service degradation. The issue was traced to an existing configuration gap that prevented application workloads from utilizing the platform's DNS caching capability. As a result, DNS requests continued to follow the standard resolution path, creating unnecessary network overhead and contributing to DNS request saturation under higher traffic volumes. While this condition had existed for some time without widespread impact, continued platform growth, increased workload density, and infrastructure scaling changes increased DNS traffic and exposed the underlying limitation. Once the DNS processing limits were reached, requests were intermittently dropped, resulting in cascading application failures and customer-facing service disruptions. During the investigation, engineers implemented several mitigations to reduce customer impact while continuing to identify the underlying cause. However, because these actions addressed symptoms rather than the root issue, the condition recurred and resulted in multiple major incidents before a permanent corrective solution was implemented. ## Corrective Actions **Detection:** The failure condition triggered system alarms, prompting engineers to initiate incident response procedures to validate, investigate, and reproduce the issue. While the investigation was underway, some customers reported service degradation when accessing and using the CXone Mpower Expert knowledge portal. **Remediation:** The impact was mitigated after engineers scaled up resources and implemented a node local DNS cache. Service stability was further improved as traffic volumes decreased, allowing the platform to recover and return to normal operation. Completed on 07/01/2026. **Prevention:** Engineers developed a dashboard to monitor local DNS cache performance, improving visibility into DNS health and enabling earlier detection, investigation, and remediation of potential issues before they impact service availability or customer experience. Completed on 07/01/2026. The Engineering team implemented an emergency change to correctly enable local DNS caching for applicable workloads, reducing DNS traffic, preventing node-level DNS saturation, and restoring the intended DNS architecture. This improved platform stability and DNS performance while reducing the risk of similar incidents. Additional infrastructure optimizations were also implemented to improve operational efficiency and minimize service impact during scaling activities. Completed on 07/02/2026. Engineers will conduct a comprehensive validation of DNS configurations across all workloads to ensure consistent use of node local DNS cache. While the immediate issue has been remediated, a fleet-wide review will identify and correct any remaining configuration gaps, helping to optimize DNS performance, reduce infrastructure load, and prevent similar service degradation events in the future. In addition, the Engineering team will continue extended monitoring of platform health and stability to verify the long-term effectiveness of the corrective actions and proactively identify any emerging issues. An update will be provided by End of Day MT on 07/17/2026. NiCE resiliency teams remain focused on enhancing system reliability, stability, platform-wide resilience, monitoring capabilities, and overall performance. These ongoing efforts are aligned with the Operational Resiliency Excellence initiative, driving continuous improvement, strengthening operational maturity, and delivering measurable business outcomes. ## Incident Timeline \(UTC\) 07/01/2026 07:55 AM \(UTC\) - Engineers received a service degradation alert and immediately initiated incident response procedures to investigate, validate, and reproduce the issue to determine its scope and potential customer impact. 07/01/2026 08:15 AM \(UTC\) - The first customer case was opened, and Tech Support \(TS\) engineers began the troubleshooting investigation. 07/01/2026 08:39 AM \(UTC\) - TS engineers notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. 07/01/2026 09:54 AM \(UTC\) - Engineers identified a suspected cause and Incident Timeline \(UTC\) began remediation steps. 07/01/2026 10:31 AM \(UTC\) - A fix was implemented, and engineers closely monitored system performance.

   **Impact Start Time \(UTC\) 06/26/2026 04:07 PM UTC** **Impact End Time \(UTC\) 06/26/2026 05:36 PM UTC** **Incident Summary:** On 06/26/2026, some NiCE CXone Mpower customers reported service degradation while accessing and using the CXone Mpower Expert knowledge portal. The recurring service degradation was caused by a Domain Name System \(DNS\) resolution bottleneck within the platform infrastructure during periods of elevated traffic. The issue was mitigated through an emergency change that introduced timeout controls to prevent backend processes from remaining stuck for extended periods, allowing orphaned processes to be released and system resources to be recovered. Service stability was further aided by a reduction in traffic volume. ## Root Cause The recurring service degradation was caused by a DNS resolution bottleneck within the platform infrastructure during periods of elevated traffic. Increased DNS request volume exceeded infrastructure processing limits, resulting in intermittent DNS lookup failure. These failures triggered application retries, increased latency, elevated “5xx” errors, and customer-facing service degradation. The issue was traced to an existing configuration gap that prevented application workloads from utilizing the platform's DNS caching capability. As a result, DNS requests continued to follow the standard resolution path, creating unnecessary network overhead and contributing to DNS request saturation under higher traffic volumes. While this condition had existed for some time without widespread impact, continued platform growth, increased workload density, and infrastructure scaling changes increased DNS traffic and exposed the underlying limitation. Once the DNS processing limits were reached, requests were intermittently dropped, resulting in cascading application failures and customer-facing service disruptions. During the investigation, engineers implemented several mitigations to reduce customer impact while continuing to identify the underlying cause. However, because these actions addressed symptoms rather than the root issue, the condition recurred and resulted in multiple major incidents before a permanent corrective solution was implemented. ## Corrective Actions **Detection:** The failure condition triggered system alarms, prompting engineers to initiate incident response procedures to validate, investigate, and reproduce the issue. While the investigation was underway, some customers reported service degradation when accessing and using the CXone Mpower Expert knowledge portal. **Remediation:** The issue was mitigated through an emergency change that introduced timeout controls to prevent backend processes from remaining stuck for extended periods, allowing orphaned processes to be released and system resources to be recovered. Service stability was further aided by a reduction in traffic volume. Completed on 06/26/2026. **Prevention:** Engineers developed a dashboard to monitor local DNS cache performance, improving visibility into DNS health and enabling earlier detection, investigation, and remediation of potential issues before they impact service availability or customer experience. Completed on 07/01/2026. The Engineering team implemented an emergency change to correctly enable local DNS caching for applicable workloads, reducing DNS traffic, preventing node-level DNS saturation, and restoring the intended DNS architecture. This improved platform stability and DNS performance while reducing the risk of similar incidents. Additional infrastructure optimizations were also implemented to improve operational efficiency and minimize service impact during scaling activities. Completed on 07/02/2026. Engineers will conduct a comprehensive validation of DNS configurations across all workloads to ensure consistent use of node local DNS cache. While the immediate issue has been remediated, a fleet-wide review will identify and correct any remaining configuration gaps, helping to optimize DNS performance, reduce infrastructure load, and prevent similar service degradation events in the future. In addition, the Engineering team will continue extended monitoring of platform health and stability to verify the long-term effectiveness of the corrective actions and proactively identify any emerging issues. An update will be provided by End of Day MT on 07/17/2026. NiCE resiliency teams remain focused on enhancing system reliability, stability, platform-wide resilience, monitoring capabilities, and overall performance. These ongoing efforts are aligned with the Operational Resiliency Excellence initiative, driving continuous improvement, strengthening operational maturity, and delivering measurable business outcomes. ## Incident Timeline \(UTC\) 06/26/2026 04:07 PM \(UTC\) - Engineers received a service degradation alert and immediately initiated incident response procedures to investigate, validate, and reproduce the issue to determine its scope and potential customer impact. 06/26/2026 04:10 PM \(UTC\) - The first customer case was opened, and Tech Support \(TS\) engineers began the troubleshooting investigation. 06/26/2026 04:35 PM \(UTC\) - TS engineers notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. 06/26/2026 04:55 PM \(UTC\) - Engineers identified a suspected cause and began remediation steps. 06/26/2026 05:36 PM \(UTC\) - The impact was resolved after implementing timeout controls to prevent backend processes from becoming stalled and as traffic levels returned to normal.

   **Major Incident# 02796435** **Impact Start Time \(UTC\) 05/12/2026 02:50 PM UTC** **Impact End Time \(UTC\) 05/12/2026 03:36 PM UTC** ### Incident Summary Updated on 05/22/2026 - On 05/12/2026, some NiCE CXone Knowledge customers experienced slowness when accessing sites, while others were unable to access the platform entirely with a “504 Gateway Timeout” error within the CXone Knowledge portal. The recurring service degradation incidents were caused by increased traffic volumes combined with performance limitations in certain backend processes, primarily impacting the US regional platform due to higher demand. The impact was mitigated after restarting the affected pods, which restored platform stability ### Root Cause The recurring service degradation incidents were caused by increased traffic volumes combined with performance limitations in certain backend processes, primarily impacting the US regional platform due to higher demand. Under elevated traffic conditions, including automated crawler activity, some requests followed less optimized processing paths, increasing system load. This was further amplified by legacy or complex page content requiring more intensive processing. While scaling actions helped restore capacity, they also introduced temporary overhead that contributed to intermittent performance degradation. Additionally, although autoscaling functioned as designed, it reached its limits and was insufficient to address constraints related to per-pod Central Processing Unit \(CPU\) capacity. ### Corrective Actions **Detection:** Internal support teams detected partial service failures through proactive alerting and monitoring. Subsequently, engineers received customer reports of slowness when accessing sites within the CXone Knowledge portal. **Remediation:** The impact was mitigated after restarting the affected pods, which restored platform stability. Completed on 05/12/2026. **Prevention:** The Engineering team implemented interim mitigation measures to maintain system stability and ensure consistent performance while permanent improvements are finalized and deployed. Completed on 05/12/2026. Baseline system capacity was increased by raising the minimum number of pods and allocating higher CPU resources. This ensures sufficient resources are consistently available, reduces reliance on dynamic scaling, and improves overall system stability during periods of increased demand. Completed on 05/12/2026. The Engineering team will implement targeted software optimizations, including improvements to a specific endpoint that previously introduced cascading effects during scaling events. These enhancements are designed to reduce resource contention and improve system efficiency under high load conditions. The changes are currently undergoing validation and will be deployed following comprehensive testing. Completed on 05/21/2026. The Engineering team will enhance alert notification delivery to ensure alarms are reliably triggered and routed to the appropriate response teams as expected, enabling faster detection and more timely corrective action when issues arise. Completed on 05/22/2026. ### Incident Timeline \(UTC\) 5/12/2026 02:50 PM \(UTC\) - Engineers identified partial service failures through proactive alerting and monitoring. A corresponding service disruption notification was promptly published on the Status Health page while engineers initiated their investigation and remediation efforts to prevent customer impact. 5/12/2026 03:09 PM \(UTC\) - The first customer case was opened, and Tech Support \(TS\) engineers began their initial validation and troubleshooting investigation. 5/12/2026 03:27 PM \(UTC\) - TS engineers notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. 5/12/2026 03:36 PM \(UTC\) - The impact was resolved after engineers restarted the affected pods and validated recovery through internal testing, marking the end of customer impact. Following confirmation of sustained stability and no further customer impact, the incident was subsequently marked as resolved.

   **Impact Start Time \(UTC\) 04/29/2026 10:31 AM UTC** **Impact End Time \(UTC\) 04/29/2026 11:56 AM UTC** **Incident Summary** On 04/29/2026, some NiCE CXone Mpower customers initially experienced slowness when accessing sites within the CXone Mpower Expert knowledge portal. The issue subsequently worsened, leading to complete inaccessibility, with users encountering “503 Service Unavailable” and “504 Gateway Timeout” errors. The service disruption was caused by a short-term resource saturation within one of the platform’s backend Application Programming Interface \(API\)\* components. The issue was resolved by scaling up multiple services, increasing Central Processing Unit \(CPU\) allocation per-pod to better handle traffic spikes, and restarting the affected API services to apply the updated resource configurations, restoring normal service operation. **Root Cause** The service disruption was caused by a short-term resource saturation within one of the platform’s backend API components. Under certain conditions, a burst of long running requests placed higher than expected demand on processing resources, leading to slower response times and errors for some customers. Certain subset of API requests required significantly more CPU than others. When many of these requests were processed concurrently, CPU utilization on affected pods became saturated, causing requests to slow down or time out. This saturation cascaded to upstream services, more broadly impacting site availability. Although a built in autoscaling mechanism was in place and functioned as designed, it reached its maximum limit and proved insufficient because the underlying issue was related to per-pod CPU constraints rather than the number of pods. The observed workload pattern required additional per-service processing capacity to compensate for these limitations and restore stable operation. ### Corrective Actions: **Detection:** Although a builtin alerting mechanism was in place to detect the failure condition, the alarm did not trigger to the responsible team as expected. Subsequently, internal support teams began receiving customer reports of slowness when accessing sites within the CXone Mpower Expert knowledge portal. The condition later escalated to complete service inaccessibility, with users encountering “503 Service Unavailable” and “504 Gateway Timeout” errors. **Remediation:** The issue was resolved by scaling up multiple services, increasing CPU allocation per-pod to better handle traffic spikes, and restarting the affected API services to apply the updated resource configurations, restoring normal service operation. Completed on 04/29/2026. **Prevention:** The Engineering team will enhance alert notification delivery to ensure alarms are reliably triggered and routed to the appropriate response teams as expected, enabling faster detection and more timely corrective action when issues arise. An update will be provided by End of Day \(EOD\) MT on 05/15/2026. While the risk of recurrence is currently low following the increase in resource capacity, the Engineering team will implement targeted performance improvements to the affected API component that contributed to this incident. In addition, code level safeguards will be introduced to ensure that, under similar conditions, inefficient requests are terminated sooner, and system resources are released more quickly. These measures are intended to enable faster failure handling and prevent prolonged CPU saturation. An update will be provided by EOD MT on 06/05/2026. **Incident Timeline \(UTC\)** 04/29/2026 10:31 AM \(UTC\) - Telemetry detected initial slow responses and timeout errors, marking the start of customer impact. 04/29/2026 10:51 AM \(UTC\) - The first customer case opened, and Tech Support \(TS\) engineers began the troubleshooting investigation. 04/29/2026 11:20 AM \(UTC\) - TS engineers notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. 04/29/2026 11:41 AM \(UTC\) - Engineers identified a suspected cause and began remediation steps. 04/29/2026 11:56 AM \(UTC\) - The issue was resolved after scaling up resources and restarting the affected API services.

   **Impact Start Time \(UTC\)** - 03/16/2026 12:55 PM UTC **Impact End Time \(UTC\)** - 03/16/2026 01:44 PM UTC ## **Incident Summary** Updated on 03/24/2025 - On 03/16/2026, some NiCE CXone Mpower customers experienced degraded performance and intermittent errors within the CXone Mpower Expert application. The impact was caused by elevated system utilization resulting from increased traffic load, which placed excessive demand on the high-availability load-balancing layer. This led to increased response times and reduced request processing efficiency. The impact was resolved when engineers increased the pod capacity of both the web application tier and the load balancer later, thereby restoring system throughput, stabilizing response times, and returning the platform to normal operating conditions. ## **Root Cause** The impact was caused by elevated system utilization resulting from increased traffic load, which placed excessive demand on the high-availability load-balancing layer. This led to increased response times and reduced request processing efficiency. Further investigation determined that the performance degradation was caused by a combination of constrained application processing capacity and insufficient load-balancing scale under peak traffic conditions. Web worker throughput was limited due to a known performance constraint, which reduced the rate at which incoming requests could be processed. This condition was further amplified by the load balancing layer operating below its expected production capacity, resulting in suboptimal traffic distribution and increased system latency during periods of elevated demand. Engineering teams are implementing targeted preventive actions to improve auto-scaling responsiveness and ensure the timely promotion of critical performance fixes to production. ## **Corrective Actions** **Detection:** Internal teams received alerts indicating increased of high availability load balancer response times. Shortly after, customers reported degraded performance and intermittent errors within the CXone Mpower Expert application. **Remediation:** The impact was resolved when engineers increased the pod capacity of both the web application tier and the load balancer later, thereby restoring system throughput, stabilizing response times, and returning the platform to normal operating conditions. Completed on 03/16/2026. **Prevention:** Engineers will adjust the auto-scaling policies to improve responsiveness and enable more aggressive scale-out behavior during peak traffic periods, ensuring capacity aligns with demand in near real time. An update will be provided by End of Day \(EOD\) MT on 03/26/2026. Engineers will implement auto-scaling for the high-availability load-balancing layer to ensure traffic distribution capacity scales proportionally with application workload. An update will be provided by EOD MT on 03/26/2026. ## **Incident Timeline \(UTC\)** 03/16/2026 12:55 PM \(UTC\) - First customer case opened, and Tech Support \(TS\) engineers began the troubleshooting investigation. 03/16/2026 01:07 PM \(UTC\) - TS engineers notified the Network Operations Center \(NOC\) engineers about the reported customer impact; a major incident was proposed and confirmed. 03/16/2026 01:44 PM \(UTC\) - Impact was resolved after engineers made an increase in available resources and internal tests were successful.

   **Impact Start Time** 03/03/2026 02:24 PM UTC **Impact End Time** 03/03/2026 05:00 PM UTC **Incident Summary** Updated on 03/11/2026 - On 3/3/2026, some NiCE CXone Mpower customers elevated latency within the CXone Expert application, resulting in delayed retrieval of knowledge-base articles and impacting agents’ ability to efficiently access customer support content. The impact stemmed from a processing latency issue within the application layer. The impact was resolved when engineers restored normal service by scaling up the infrastructure components responsible for handling inbound web requests, ensuring sufficient processing capacity to stabilize throughput and eliminate request bottlenecks. **Root Cause** The root cause stemmed from a processing latency issue for the application layer. The system briefly took longer than usual to handle requests. For a short period, more activity came in than the system typically manages at once, which slowed things down. As a result, some requests took longer to finish and a few timed out, leading to the performance issues customers noticed. **Corrective Actions** _Detection_: Internal support teams received a customer reported issue and confirmed an ongoing latency issue with the CXone Expert application. _Remediation_: Engineers restored normal service by scaling up the infrastructure components responsible for handling inbound web requests, ensuring sufficient processing capacity to stabilize throughput and eliminate request bottlenecks. Completed on 03/03/2026. _Prevention_: The Engineering team developed and deployed a code fix to address an underlying issue with instance scaling.
