Code view fails to load when content contains some non-ASCII characters

Resolved - Starting February 26, 2026 at 22:10 UTC through February 27, 05:50 UTC, the repository browsing UI was degraded and users were unable to load pages for files and directories with non-ASCII characters (including Japanese, Chinese, and other non-Latin scripts). On average, the error rate was 0.014% and peaked at 0.06% of requests to the service. Affected users saw 404 errors when navigating to repository directories and files with non-ASCII names. This was due to a code change that altered how file and directory names were processed, which caused incorrectly formatted data to be stored in an application cache.

We mitigated the incident by deploying a fix that invalidated the affected cache entries and progressively rolling it out across all production environments.

We are working to improve our pre-production testing to cover non-ASCII character handling, establish better cache invalidation mechanisms, and enhance our monitoring to detect this type of failure mode earlier, to reduce our time to detection and mitigation of issues like this one in the future.
Feb 27, 06:04 UTC

Update - We have cleared all caches and everything is operating normally.
Feb 27, 06:03 UTC

Update - We have mitigated the issue but are working on invalidating caches in order to fix the issue for all impacted repos.

Code search experiencing degraded performance

Resolved - Between 2026-02-23 19:10 and 2026-02-24 00:46 UTC, all lexical code search queries in GitHub.com and the code search API were significantly slowed, and during this incident, between 5 and 10% of search queries timed out. This was caused by a single customer who had created a network of hundreds of orchestrated accounts which searched with a uniquely expensive search query. This search query concentrated load on a single hot shard within the search index, slowing down all queries. After we identified the source of the load and stopped the traffic, latency returned to normal.

To avoid this situation occurring again in the future, we are making a number of improvements to our systems, including: improved rate limiting that accounts for highly skewed load on hot shards, improved system resilience for when a small number of shards time out, improved tooling to recognize abusive actors, and capabilities that will allow us to shed load on a single shard in emergencies.
Feb 24, 00:46 UTC

Update - We have identified a cause for the latency and timeouts and have implemented a fix. We are observing initial recovery now.
Feb 24, 00:38 UTC

Update - Customers using code search continue to see increased latency and timeout errors. We are working to mitigate issues on the affected shard.

Incident with Issues and Pull Requests Search

Resolved - On February 23, 2026, between 21:01 UTC and 21:30 UTC the Search service experienced degraded performance, resulting in an average of 3.5% of search requests for Issues and Pull Requests being rejected. During this period, updates to Issues and Pull Requests may not have been immediately reflected in search results.

During a routine migration, we observed a spike in internal traffic due to a configuration change in our search index. We were alerted to the increase in traffic as well as the increase in error rates and rolled back to the previous stable index.

We are working to enable more controlled traffic shifting when promoting a new index to allow us to detect potential limitations earlier and ensure these operations succeed in a more controlled manner.
Feb 23, 21:30 UTC

Update - Some customers are seeing timeout errors when searching for issues or pull requests. Team is currently investigating a fix.

Extended job start delays for larger hosted runners

Resolved - On February 20, 2026, between 17:45 UTC and 20:41 UTC, 4.2% of workflows running on GitHub Larger Hosted Runners were delayed by an average of 18 minutes. Standard, Mac, and Self-Hosted Runners were not impacted.

The delays were caused by communication failures between backend services for one deployment of larger runners. Those failures prevented expected automated scaling and provisioning of larger hosted runner capacity within that deployment. This was mitigated when the affected infrastructure was recycled, larger runner pools in the affected deployment successfully scaled up, and queued jobs processed.

We are working to improve the time to detect and diagnose this class of failures and improve the performance of recovery mechanisms for this degraded network state. In addition, we have architectural changes underway that will enable other deployments to pick up work in similar situations, so there is no customer impact due to deployment-specific infrastructure issues like this.
Feb 20, 20:41 UTC

Update - The team continues to investigate issues with some larger runner jobs being queued for a long time. We are though seeing improvement in the queue times. We will continue providing updates on the progress towards mitigation.

Intermittent authentication failures on GitHub

Resolved - On February 17, 2026, between 17:07 UTC and 19:06 UTC, some customers experienced intermittent authentication failures affecting GitHub Actions, parts of Git operations, and other authentication-dependent requests. On average, the Actions error rate was approximately 0.6% of affected API requests. Git operations ssh read error rate was approximately 0.29%, while ssh write and http operations were not impacted. During the incident, a subset of requests failed due to token verification lookups intermittently failing, leading to 401 errors and degraded reliability for impacted workflows.

The issue was caused by elevated replication lag in the token verification database cluster. In the days leading up to the incident, the token store’s write volume grew enough to exceed the cluster’s available capacity. Under peak load, older replica hosts were unable to keep up, replica lag increased, and some token lookups became inconsistent, resulting in intermittent authentication failures.

We mitigated the incident by adjusting the database replica topology to route reads away from lagging replicas and by adding/bringing additional replica capacity online. Service health improved progressively after the change, with GitHub Actions recovering by ~19:00 UTC and the incident resolved at 19:06 UTC.

We are working to prevent recurrence by improving the resilience and scalability of our underlying token verification data stores to better handle continued growth.
Feb 17, 19:06 UTC

Update - We are continuing to monitor the mitigation and continuing to see signs of recovery.
Feb 17, 18:55 UTC

Update - We have rolled out a mitigation and are seeing signs of recovery and are continuing to monitor.
Feb 17, 18:18 UTC

Update - We have identified a low rate of authentication failures affecting GitHub App server to server tokens, GitHub Actions authentication tokens, and git operations. Some customers may experience intermittent API request failures when using these tokens. We believe we've identified the cause and are working to mitigate impact.
