Scheduled - Codespaces will be undergoing global maintenance from May 29, 2025 21:30 UTC to May 31, 2025 4:30 UTC. Maintenance will begin in our Europe, Asia, and Australia regions. Once it is complete, maintenance will start in our US regions. Each batch of regions will take approximately three to four hours to complete.
During this time period, users may experience intermittent connectivity issues when creating new Codespaces or accessing existing ones.
To avoid disruptions, ensure that any uncommitted changes are committed and pushed before the maintenance starts. Codespaces with uncommitted changes will remain accessible as usual after the maintenance is complete.

On May 28, 2025, from approximately 09:45 UTC to 14:45 UTC, GitHub Actions experienced delayed job starts for workflows in public repos using Ubuntu-24 standard hosted runners. This was caused by a misconfiguration in backend caching behavior after a failover, which led to duplicate job assignments and reduced available capacity. Approximately 19.7% of Ubuntu-24 hosted runner jobs on public repos were delayed. Other hosted runners, self-hosted runners, and private repo workflows were unaffected.
By 12:45 UTC, we mitigated the issue by redeploying backend components to reset state and scaling up available resources to more quickly work through the backlog of queued jobs. We are working to improve our deployment and failover resiliency and validation to reduce the likelihood of similar issues in the future.

On May 27, 2025, between 09:31 UTC and 13:31 UTC, some Actions jobs experienced failures uploading to and downloading from the Actions Cache service. During the incident, 6% of all workflow runs couldn’t upload or download cache entries from the service, resulting in a non-blocking warning message in the logs and performance degradation. The disruption was caused by an infrastructure update related to the retirement of a legacy service, which unintentionally impacted Cache service availability. We resolved the incident by reverting the change and have since implemented a permanent fix to prevent recurrence.
We are improving our configuration change processes by introducing additional end-to-end tests to cover the identified gaps, and implementing deployment pipeline improvements to reduce mitigation time for similar issues in the future.

Between 10:00 and 20:00 UTC on May 27, a change to our git proxy service resulted in some git client implementations not being able to consistently push to GitHub. Reverting the change resulted in an immediate resolution of the problem for all customers. The inflated time to detect this failure was due to the relatively few impacted clients. We are re-evaluating the proposed change to understand how we can
prevent and detect such failures in the future.

On May 26, 2025, between 06:20 UTC and 09:45 UTC GitHub experienced broad failures across a variety of services (API, Issues, Git, etc). These were degraded at times, but peaked at 100% failure rates for some operations during this time.
On May 23, a new feature was added to Copilot APIs and monitored during rollout but it was not tested at peak load. At 6:20 UTC on May 26, load increased on the code path in question and started to degrade a Copilot API because the caching for this endpoint and circuit breakers for high load were misconfigured.
In addition, the traffic limiting meant to protect wider swaths of the GitHub API from queuing was not yet covering this endpoint, meaning it was able to overwhelm the capacity to serve traffic and cause request queuing.
We were able to mitigate the incident by turning off the endpoint until the behavior could be reverted.
We are already working on a quality of service strategy for API endpoints like this that will limit the impact of a broad incident and are rolling it out. We are also addressing the specific caching and circuit breaker misconfigurations for this endpoint, which would have reduced the time to mitigate this particular incident and the blast radius.

On May 23, 2025, between 17:40 UTC and 18:30 UTC public API and UI requests to read and write Git repository content were degraded and triggered user-facing 500 responses. On average, the error rate was 61% and peaked at 88% of requests to the service. This was due to the introduction of an uncaught fatal error in an internal service. A manual rollback was required which increased the time to remediate the incident.
We are working to automatically detect and revert a change based on alerting to reduce our time to detection and mitigation. In addition, we are adding relevant test coverage to prevent errors of this type getting to production.

On May 22, 2025, between 07:06 UTC and 09:10 UTC, the Actions service experienced degradation, leading to run start delays. During the incident, about 11% of all workflow runs were delayed by an average of 44 minutes. A recently deployed change contained a defect that caused improper request routing between internal services, resulting in security rejections at the receiving endpoint. We resolved this by reverting the problematic change and are implementing enhanced testing procedures to catch similar issues before they reach production environments.

On May 20, 2025, between 18:18 UTC and 19:53 UTC, Copilot Code Completions were degraded in the Americas. On average the error rate was 50% of requests to the service in the affected region. This was due to a misconfiguration in load distribution parameters after a scale down operation.

On May 20, 2025, between 12:09 PM UTC and 4:07 PM UTC, the GitHub Copilot service experienced degraded availability, specifically for the Claude Sonnet 3.7 model. During this period, the success rate for Claude Sonnet 3.7 requests was highly variable, down to approximately 94% during the most severe spikes. Other models remained available and working as expected throughout the incident.
The issue was caused by capacity constraints in our model processing infrastructure that affected our ability to handle the large volume of Claude Sonnet 3.7 requests.
We mitigated the incident by rebalancing traffic across our infrastructure, adjusting rate limits, and working with our infrastructure teams to resolve the underlying capacity issues. We are working to improve our infrastructure redundancy and implementing more robust monitoring to reduce detection and mitigation time for similar incidents in the future.

Between May 16, 2025, 1:21 PM UTC and May 17, 2025, 2:26 AM UTC, the GitHub Enterprise Importer service was degraded and experienced slow processing of customer migrations. Customers may have seen extended wait times for migrations to start or complete.
This incident was initially observed as a slowdown in migration processing. During our investigation, we identified that a recent change aimed at improving API query performance caused an increase in load signals, which triggered migration throttling. As a result, the performance of migrations was negatively impacted, and overall migration duration increased. In parallel, we identified a race condition that caused a specific migration to be repeatedly re-queued, further straining system resources and contributing to a backlog of migration jobs, resulting in accumulated delays. No data was lost, and all migrations were ultimately processed successfully.
We have reverted the feature flag associated with a query change and are working to improve system safeguards to help prevent similar race condition issues from occurring in the future.
