**Date:** October 29, 2025 **Impact Duration:** 15:55 – 21:20 UTC **Status:** Resolved **Root Cause:** Outage with our cloud hosting provider ### **Overview** On **October 29, 2025**, Mural experienced a major service disruption that prevented users from signing in or accessing their murals. The issue was caused by a widespread outage with our primary cloud hosting provider. While the outage was external to Mural, it significantly impacted our ability to serve requests and maintain normal operations for several hours. ### **Timeline of Events \(UTC\)** * **15:55** — We detected that some users were unable to sign in to Mural. Mural’s incident response team began investigating immediately * **16:13** — The incident notification was posted to Mural’s status page at [status.mural.co](http://status.mural.co)  * **16:17** — We identified the root cause as an outage in Microsoft Azure’s infrastructure affecting application access * **16:32 – 20:46** — We continued working with Microsoft Azure and monitored for recovery while keeping users informed via our status page * **20:46** — Partial recovery began; some regions regained access * **21:19** — Full service restoration confirmed * **23:20** — Incident marked as **resolved** after stable monitoring and confirmation from our upstream provider ### **Root Cause** The outage originated from an **Azure Front Door incident** that disrupted network resources across several regions. This affected authentication and access for users attempting to sign in to Mural. Our systems rely on Azure for critical infrastructure, meaning our service availability was directly impacted by the Azure outage. ### **Resolution** We attempted several workarounds during the Azure outage, however these proved unsuccessful as the core issue required Azure Front Door accessibility. As Azure recovered, we were able to reconfigure our systems to bring Mural services back online. We closely monitored all internal systems and user traffic to ensure full stability before marking the incident as ‘in monitoring’. Once normal operation was confirmed across all regions for a period of 2 hours, we closed the incident. ### **What We’re Doing Next** Although this incident was triggered by an external provider, we are taking several steps to reduce the impact of similar events in the future: 1. **CDN Improvements** — We are researching improvements to our content delivery network \(CDN\) setup to enhance resilience 2. **Enhanced Monitoring** — We are expanding our monitoring systems to detect upstream provider issues faster and more precisely 3. **Communication Consistency** — We are working on improving how we communicate during incidents across all channels, including our status page, marketing site, and in-app messages, to ensure consistent and timely updates 4. **Cloud Infrastructure** — We continue to assess our infrastructure to mitigate any potential impact from potential future impacts to our cloud hosting provider ### **Closing Thoughts** We know how important Mural is for your daily collaboration and creative work. Any downtime disrupts your teams, and we take that responsibility seriously. We sincerely apologize for the inconvenience this incident caused and appreciate your patience as we worked to resolve it. We’re committed to learning from this event and strengthening Mural’s resilience against external dependencies.

**What happened:** At 17:10 CET on March 6th, 2024, we updated the IP allowlisting settings for one of our Enterprise customers. The list of IP addresses contained ranges used by a 3rd party cloud security provider, which prevented a subset of customers from accessing Mural. We started to receive reports of access issues and immediately engaged our incident task force to investigate. The incorrect IP address configuration was quickly identified as the cause of the access issues. We rolled back the change and full access was restored at 17:50 CET. ‌ **What we’ve done to avoid this happening again:** We have implemented additional checks on IP address restrictions, whilst our engineers work on product enhancements to prevent this issue from re-occurring.

**Summary**:  On Saturday, November 11th at 03:00 UTC, Mural performed scheduled maintenance on our production clusters. Post-migration checks indicated all functions were performing as expected. On Monday, November 13th, some Mural customers reported difficulty logging into the Mural web application. Mural’s incident response team was immediately engaged in troubleshooting these reports. Initial investigations revealed that the platform upgrade over the preceding weekend had incorrect settings for the DNS infrastructure and a key backend application's auto-scaling. This resulted in unstable connections for some users. During the course of this investigation, we also discovered that load balancing improvements for clients with specific network and application configurations altered how the client’s IP address was interpreted by our system, preventing access for such clients.  Our incident response team addressed the auto-scaling configuration, resolving DNS-related issues and restored access for the majority of users. Next, a new load-balancing configuration underwent adjustments and testing to restore stable connections for the previously-impacted users. The total time from when our incident response team started working on this incident, to deploying the final fix, was 9 hours 40 minutes. **What we’ve done to prevent this happening again:** As part of Mural’s post-incident procedure, our engineering teams conducted a thorough review to identify the root cause and outline necessary improvements. 8 separate changes have been identified and will be implemented in the coming weeks. These changes cover monitoring to detect this scenario sooner, enhanced post-migration checks to ensure this scenario and others are included in our use cases and reviewing our migration process to reduce the risks. We apologize for any inconvenience this incident may have caused and sincerely thank your patience whilst we worked through this incident.
