Resolved - On December 23, 2025, between 09:15 UTC and 10:32 UTC the Issues and Pull Requests search indexing service was degraded and caused search results to contain stale data up to 3 minutes old for roughly 1.3 million issues and pull requests. This was due to search indexing queues backing up from resource contention caused by a running transition.

We mitigated the incident by cancelling the running transition.

We are working to implement closer monitoring of search infrastructure resource utilization during transitions to reduce our time to detection and mitigation of issues like this one in the future.

Dec 23, 10:32 UTC
Update - Issues and Pull Requests are operating normally.
Dec 23, 10:32 UTC
Update - We are seeing recovery in search indexing for Issues and Pull Requests. The queue has returned to normal processing times, and we continue to monitor service health. We'll post another update by 11:00 UTC.
Dec 23, 10:29 UTC
Update - We're experiencing delays in search indexing for Issues and Pull Requests. Search results may show data up to three minutes old due to elevated processing times in our indexing pipeline. We're working to restore normal performance. We'll post another update by 10:30 UTC.

Investigating - We are investigating reports of degraded performance for Issues and Pull Requests

Resolved - On December 22, 2025, between 22:01 UTC and 22:32 UTC, unauthenticated requests to github.com were degraded, resulting in slow or timed out page loads and API requests. Unauthenticated requests from Actions jobs, such as release downloads, were also impacted. Authenticated traffic was not impacted. This was due to a severe spike in traffic, primarily to search endpoints.

Our immediate response focused on identifying and mitigating the source of the traffic increase, which along with automated traffic management restored full service for our users.

We improved limiters for load to relevant endpoints and are continuing work to more proactively identify these large changes in traffic volume, improve resilience in critical request flows, and improve our time to mitigation.

Dec 23, 00:17 UTC
Update - All services at healthy levels. We're finalizing the change to prevent future degradations from the same source.
Dec 23, 00:06 UTC
Update - We're investigating elevated traffic affecting GitHub services, primarily impacting logged-out users with some increased latency on Issues. We're preparing additional mitigations to prevent further spikes.
Dec 22, 23:32 UTC
Update - We are experiencing elevated traffic affecting some GitHub services, primarily impacting logged-out users. We're actively investigating the full scope and working to restore normal service. We'll post another update by 23:45 UTC.
