Reporting data reprocessed for February 20, 2026
Timeline · 1 update
- resolved Feb 26, 2026, 07:47 PM UTC
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.
Some customers are receiving a "No Sites Found" error in response to Decision API requests.

Degraded Ad Serving for EU Central 1
Timeline · 1 update
- resolved Nov 26, 2025, 08:27 PM UTC
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.
