Kevel outage history

Between approximately 06:30 and 06:42 UTC on October 15, 2026, ad serving in EU-Central-1 experienced elevated response times and intermittent errors on decision requests. Service has recovered, and no customer action is required.

We are currently investigating an issue impacting some users saving changes made to Ads through the Ad Server UI. Changes made through the Management API are not affected. We have identified a likely cause and are working to resolve it.

A fix has been deployed and saving changes in the Ad Server UI is working as expected. We are continuing to monitor.

Confirming this is now resolved. Please find a summary below. Between ~19:38 and ~22:35 UTC on September 17, 2026, saving an ad through the Ad Server UI may have returned an error even though the change was applied successfully. Users who retried after seeing the error may have created duplicate ads. We recommend reviewing any ads created or edited during this window and removing any duplicates.

Between 21:36 and 21:54 UTC on September 9, 2026, ad serving in US-East-1 experienced elevated response times and intermittent errors on decision requests. Service recovered on its own, and no customer action is required.

We are currently investigating an issue that is causing degraded Ad Serving for customers in the EU Central 1 region.

The issue has been identified and a fix is being implemented.

We are continuing to work on a fix for this issue.

A fix has been implemented and we are monitoring the results.

This incident has been resolved.

We identified an issue that may have delayed delivery of beta log data via Data Shipping for some customers between June 9, 2026 at 21:16 UTC and June 11, 2026 at 14:18 UTC. June 11, 2026, 14:18 UTC: This issue has been resolved. Beta logs are now being shipped as expected, and no log data was lost. We are actively working to deliver any delayed logs from the affected period. June 12, 2026, 12:30 UTC: Confirming the backfill of all delayed data from the impacted period is complete.

We are currently investigating degraded ad serving performance in the us-east-1 region.

We are continuing to investigate the root cause. In the meantime, we have scaled additional capacity in the affected region, which has restored stability to ad serving. We will provide further updates as we learn more.

A mitigation has been applied and we are currently monitoring the system to ensure continued stability.

System performance has remained stable following the applied mitigation. We are continuing to monitor to ensure ongoing reliability.

The issue has been resolved and system performance has remained stable. We will continue to monitor as a precaution.

Some reporting data did not process correctly between 2026-02-20 21:00:00 and 2026-02-20 22:00:00 UTC. We have since reprocessed the affected data. As a result, some reporting metrics for that time period may have increased. Additionally, in cases where clicks or conversions were fired late for ads delivered previously, the associated clicks and click-derived revenue were applied to the original delivery dates, resulting in updates to historical metrics.

We have identified an issue impacting ad serving. An investigation is underway with our team. We'll keep you updated along the way.

A fix has been implemented and we are monitoring the results.

This incident has been resolved. Issue began: 1:55 PM ET Issue resolved: 4:37 PM ET

We are investigating an issue with delayed reporting data ingestion that is causing degraded reporting performance. Some customers may experience missing data in reports for December 2 - 3.

The issue has been identified and a fix is in-progress. To further clarify the impact, some customers may be temporarily missing data from December 2 - 3, as the ingestion of this data is delayed.

Work is still in progress on the fix for delayed data ingestion. We will update again as soon as we have further progress to share.

A fix has been implemented and we are monitoring results. We expect that it will take around 8 hours for the ingestion of the delayed reporting data to be completed. Once completed, the temporarily missing reporting data from December 2 - 3 will be available.

Confirming the ingestion of the delayed reporting data is now complete and this is now resolved. Newly created reports will contain correct and up to date metrics from December 2 - 3.

Customers in the eu-central-1 region may have experienced periods of high decision response times between 06:10 and 08:05 UTC on November 24, 2025. This was caused by anomalous behavior while the Kevel system scaled in response to irregular traffic patterns. Kevel's core ad serving systems are designed to mitigate these situations and we've adjusted our scaling algorithms following this investigation to reduce the likelihood of recurrence.

US-East-1 services including ad serving in the region, authentication, campaign management and reporting have been impacting by an underlying incident with one of our infrastructure providers. We're taking remediation steps and are continuing to monitor.

Compute resources for ad serving on US-East-1 are still experiencing increased error rates while the underlying service is being restored. Authentication, Campaign Management and Reporting are operational, but you may see elevated response times while previous failed requests are retried.

Confirming we are still working to address the impact from an incident with one of our infrastructure providers. Ad serving on US-East-1 is still experiencing increased error rates while the underlying service is being restored. Authentication, Campaign Management and Reporting are operational, but may still experience elevated response times.

We are continuing to work with our infrastructure provider to fully resolve the incident. Ad serving in the US-East-1 region remains partially impacted, with elevated error rates still observed. Authentication, Campaign Management, and Reporting remain operational, though some customers may continue to experience higher-than-normal response times. Our teams remain actively engaged, and we’ll share another update as soon as more progress is made.

We are continuing to actively respond to this incident. Ad serving in the US-East-1 region remains impacted, with elevated error rates and latency still observed. Authentication and Campaign Management remain operational, though some customers may continue to experience higher-than-normal response times. Reporting, including Data Shipping, are continuing to experience degraded performance and customers may see reports failing. Completed reports may also lack recent data. Forecast is also experiencing degraded performance and recently completed forecasts may yield less accurate results.

Ad Serving, Management and Audience continue to be operational. Data Shipping has resumed normal operations, however, customers may be missing data from today, October 20th. Confirming we will evaluate backfilling this data. Reporting and Forecasting are still operating with degraded performance. We are waiting for recovery of the related service from our infrastructure provider to resume normal operations. We anticipate this will take hours.

All Kevel services are now operational including Ad Serving, Audience, Data Shipping, Management, Forecast and Reporting. We are continuing to monitor all services. We are also still working to backfill missing data from yesterday's incident for Data Shipping and Reporting.
