We are investigating reports of impacted performance for some GitHub services.

We are investigating reports of impacted performance for some GitHub services.

GHEC Team Sync is currently degraded for enterprises with personal accounts, causing delays when syncing teams to IdP groups. We have identified the cause of the delays and are working on a mitigation. We will provide an update on our progress at 20:00 UTC.

We have deployed a mitigation. At this time GHEC Team Sync has recovered for enterprises with personal accounts. Teams syncing to IdP groups have returned to their normal cadence.

We are investigating reports of degraded performance for Copilot AI Model Providers

We are experiencing degraded availability for the Fable 5 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

We are seeing modest recovery, but are still experiencing degraded availability for the Fable 5 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

The issues with our upstream model provider have been resolved, and Fable 5 is once again available in Copilot products and IDE surfaces. We will continue monitoring to ensure stability, but mitigation is complete.

We are investigating reports of impacted performance for some GitHub services.

We are investigating issues with Login and when downloading Release Assets. We will continue to keep users updated on progress towards mitigation.

We have identified the root cause and are working on mitigation. Errors on the login page and downloading release assets have decreased, but we are not fully mitigated. We will continue to provide updates.

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

We are investigating reports of errors affecting Pull Requests and Issues on GitHub.com. Some users may encounter 500 errors when loading pull request and issue pages. Our engineering teams are actively investigating the root cause, which appears to be related to a database infrastructure issue. We will provide an update as soon as we have more information.

We are investigating reports of degraded performance for API Requests

We are investigating reports of a small increase in error rates affecting GraphQL API requests. We are working on increasing capacity and continue to investigate the increased errors. We will provide another update when we have more information

We have returned to a healthy baseline on GraphQL API requests. We will continue to work on investigations into the errors seen during this incident.

We are investigating reports of users being unable to create fine-grained Personal Access Tokens. Attempting to create a new token redirects the user back to the token overview page without an error message, but the token was not created.

We are investigating reports of degraded performance for Pages

We are investigating reports of impacted performance for some GitHub services.

We are investigating reports of degraded performance for Copilot

We are experiencing degraded availability for chat & agent models in Copilot. Multiple models are impacted and customers may experience requests failing. We are investigating and will provide an update as soon as possible.

We are still seeing intermittent errors with Copilot, and are continuing to investigate and consider mitigations.

We are investigating reports of degraded performance for Copilot AI Model Providers

We are experiencing degraded availability for the GPT-5.6 Luna model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot

We keep working with our upstream model provider, and are observing recovery. We continue monitoring to ensure stability.

The issues with our upstream model provider have been resolved, and GPT-5.6 Luna is once again available in Copilot products and IDE surfaces. We will continue monitoring to ensure stability, but mitigation is complete.

We are investigating reports of degraded performance for Copilot AI Model Providers

We are experiencing degraded availability for the Claude Fable 5 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

The issues with our upstream model provider have been resolved, and Claude Fable 5 is once again available in Copilot products and IDE surfaces. We will continue monitoring to ensure stability, but mitigation is complete.

We are investigating reports of impacted performance for some GitHub services.

This is just a test of our systems. Please ignore.

We are investigating reports of degraded availability for Actions

We are experiencing issues with GitHub Actions that are causing workflow run failures and delays for some users. Our engineering team is actively investigating the infrastructure issue and working to restore full functionality.

We have applied a mitigation for the infrastructure issue affecting GitHub Actions. Workflow run failures and delays are improving but not yet fully resolved. Our engineering team continues to work on restoring full functionality across all affected infrastructure.

We are investigating reports of degraded availability for Copilot AI Model Providers

We are experiencing degraded availability for the GPT-5.2, GPT-5.3-Codex, GPT-5.4, GPT-5.4 Mini, GPT-5.6 Sol, GPT-5.6 Terra, and GPT-5.6 Luna models in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

We are investigating reports of degraded performance for Actions

Approximately 3% of GitHub Actions runs on GitHub-hosted runners are experiencing run start delays exceeding 5 minutes. A small portion of these runs may fail after extended delays. We have identified the cause and are working on a mitigation.

The degradation affecting Actions has been mitigated. We are monitoring to ensure stability.

We are investigating reports of impacted performance for some GitHub services.

We are investigating reports of intermittent SSH authentication failures affecting connections that use deploy keys. Customers may experience failed SSH connections when interacting with repositories via deploy keys. Our engineering team is actively investigating the root cause and working toward resolution.

We have identified a recent code change as a potential cause of the SSH authentication failures affecting deploy key connections. Our engineering team is rolling back this change. Customers using deploy keys for SSH access to repositories may continue to experience intermittent connection failures until the fix is deployed.

We are investigating reports of degraded performance for Copilot AI Model Providers

We are investigating GPT Codex 5.3 performance.

We identified that an upstream provider is returning errors for GPT 5.3 Codex requests, causing some users to experience failed or interrupted responses. Traffic is being automatically rerouted to mitigate impact. We are working with the upstream provider to resolve the underlying issue. We recommend using a different model at this time while we resolve the problem.

The upstream provider continues to return intermittent errors for GPT 5.3 Codex requests. Some users may experience failed or interrupted responses when using this model. Traffic continues to be automatically rerouted to reduce impact, and we are actively working with the upstream provider on a resolution. In the meantime, selecting an alternative model will avoid disruption.

We are seeing signs of sustained recovery from the upstream provider for GPT 5.3 Codex requests. Requests are succeeding as expected. We are awaiting confirmation from the provider that the issue is fully mitigated before resolving this incident.
