Incident with Actions - Larger hosted runners

Resolved - On October 23, 2025, between 15:54 UTC and 19:20 UTC, GitHub Actions larger hosted runners experienced degraded performance, with 1.4% of overall workflow runs and 29% of larger hosted runner jobs failing to start or timing out within 5 minutes.

The full set of contributing factors is still under investigation, but the customer impact was due to database performance degradation, triggered by routine database changes causing a load profile that triggered a bug in the underlying database platform used for larger runners.

Impact was mitigated through a combination of scaling up the database and reducing load. We are working with partners to resolve the underlying bug and have paused similar database changes until it is resolved.
Oct 23, 20:25 UTC

Update - Actions is operating normally.
Oct 23, 20:25 UTC

Update - Actions larger runner job start delays and failure rates are recovering. Many jobs should be starting as normal. We're continuing to monitor and confirm full recovery.
Oct 23, 19:33 UTC

Update - We continue to investigate problems with Actions larger runners. We're continuing to see signs of improvement, but customers are still experiencing jobs queueing or failing due to timeout.
Oct 23, 18:17 UTC

Incident with API Requests

Resolved - On October 22, 2025, between 14:06 UTC and 15:17 UTC, less than 0.5% of web users experienced intermittent slow page loads on GitHub.com. During this time, API requests showed increased latency, with up to 2% timing out.

The issue was caused by elevated loads on one of our databases caused by a poorly performing query, which impacted performance for a subset of requests.

We identified the source of the load and optimized the query to restore normal performance. We’ve added monitors for early detection for query performance, and we continue to monitor the system closely to ensure ongoing stability.

Oct 22, 15:53 UTC

Update - API Requests is operating normally.
Oct 22, 15:53 UTC

Update - We have identified a possible source of the issue and there is currently no user impact but we are continuing to investigate and will not resolve this incident until we have more confidence in our mitigations and investigation results.
Oct 22, 15:17 UTC

Update - Some users may see slow, timing out requests or not found when browsing repos. We have identified slowness in our platform and are investigating.
Oct 22, 14:37 UTC

Investigating - We are investigating reports of degraded performance for API Requests

Disruption with some GitHub services

Resolved - On October 21, 2025, between 13:30 and 17:30 UTC, GitHub Enterprise Cloud Organization SAML Single Sign-On experienced degraded performance. Customers may have been unable to successfully authenticate into their GitHub Organizations during this period. Organization SAML recorded a maximum of 0.4% of SSO requests failing during this timeframe.

This incident stemmed from a failure in a read replica database partition responsible for storing license usage information for GitHub Enterprise Cloud Organizations. This partition failure resulted in users from affected organizations, whose license usage information was stored on this partition, being unable to access SSO during the aforementioned window. A successful SSO requires an available license for the user who is accessing a GitHub Enterprise Cloud Organization backed by SSO.
The failing partition was subsequently taken out of service, thereby mitigating the issue.

Remedial actions are currently underway to ensure that a read replica failure does not compromise the overall service availability.

Oct 21, 17:39 UTC

Update - Mitigation continues, the impact is limited to Enterprise Cloud customers who have configured SAML at the organization level.
Oct 21, 17:18 UTC

Update - We continuing to work on mitigation of this issue.
Oct 21, 17:11 UTC

Update - We’ve identified the issue affecting some users with SAML/OIDC authentication and are actively working on mitigation. Some users may not be able to authenticate during this time.
Oct 21, 16:33 UTC

Update - We're seeing issues for a small amount of customers with SAML/OIDC authentication for GitHub.com users. We are investigating.

Incident with Actions

Resolved - On October 21, 2025, between 07:55 UTC and 12:20 UTC, GitHub Actions experienced degraded performance. During this time, 2.11% workflow runs failed to start within 5 minutes, with an average delay of 8.2 minutes. The root cause was increased latency on a node in one of our Redis clusters, triggered by resource contention after a patching event became stuck.

Recovery began once the patching process was unstuck and normal connectivity to the Redis cluster was restored at 11:45 UTC, but it took until 12:20 UTC to clear the backlog of queued work. We are implementing safeguards to prevent this failure mode and enhancing our monitoring to detect and address problems like this more quickly in the future.
Oct 21, 12:28 UTC

Update - We were able to apply a mitigation and we are now seeing recovery.
Oct 21, 11:59 UTC

Update - We are seeing about 10% of Actions runs taking longer than 5 minutes to start, we're still investigating and will provide an update by 12:00 UTC.
Oct 21, 11:37 UTC

Update - We are still seeing delays in starting some Actions runs and are currently investigating. We will provide updates as we have more information.

Disruption with Grok Code Fast 1 in Copilot

Resolved - From October 20th at 14:10 UTC until 16:40 UTC, the Copilot service experienced degradation due to an infrastructure issue which impacted the Grok Code Fast 1 model, leading to a spike in errors affecting 30% of users. No other models were impacted. The incident was caused due to an outage with an upstream provider.
Oct 20, 16:40 UTC

Update - The issues with our upstream model provider continue to improve, and Grok Code Fast 1 is once again stable in Copilot Chat, VS Code and other Copilot products.
Oct 20, 16:39 UTC

Update - We are continuing to work with our provider on resolving the incident with Grok Code Fast 1 which is impacting 6% of users. We’ve been informed they are implementing fixes but users can expect some requests to intermittently fail until all issues are resolved.

Oct 20, 16:07 UTC

Update - We are experiencing degraded availability for the Grok Code Fast 1 model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue.

Other models are available and working as expected.
Oct 20, 14:47 UTC

Investigating - We are investigating reports of degraded performance for Copilot

Codespaces creation failling

Resolved - On October 20, 2025, between 08:05 UTC and 10:50 UTC the Codespaces service was degraded, with users experiencing failures creating new codespaces and resuming existing ones. On average, the error rate for codespace creation was 39.5% and peaked at 71% of requests to the service during the incident window. Resume operations averaged 23.4% error rate with a peak of 46%. This was due to a cascading failure triggered by an outage in a 3rd-party dependency required to build devcontainer images.

The impact was mitigated when the 3rd-party dependency recovered.

We are investigating opportunities to make this dependency not a critical path for our container build process and working to improve our monitoring and alerting systems to reduce our time to detection of issues like this one in the future.
Oct 20, 11:01 UTC

Update - We are now seeing sustained recovery. As we continue to make our final checks, we hope to resolve this incident in the next 10 minutes.
Oct 20, 10:56 UTC

Update - We are seeing early signs of recovery for Codespaces. The team will continue to monitor and keep this incident active as a line of communication until we are confident of full recovery.
Oct 20, 10:15 UTC

Update - We are continuing to monitor Codespace's error rates and will report further as we have more information.
Oct 20, 09:34 UTC

Update - We are seeing increased error rates with Codespaces generally. This is due to a third party provider experiencing problems. This impacts both creation of new Codespaces and resumption of existing ones.

We continue to monitor and will report with more details as we have them.
Oct 20, 09:01 UTC

Investigating - We are investigating reports of degraded availability for Codespaces

Disruption with push notifications

Resolved - On October 17th, 2025, between 12:51 UTC and 14:01 UTC, mobile push notifications failed to be delivered for a total duration of 70 minutes. This affected github.com and GitHub Enterprise Cloud in all regions. The disruption was related to an erroneous configuration change to cloud resources used for mobile push notification delivery.

We are reviewing our procedures and management of these cloud resources to prevent such an incident in the future.
