Resolved - Between June 19th, 2025 11:35 UTC and June 20th, 2025 11:20 UTC the GitHub Mobile Android application was unable to login new users. The iOS app was unaffected.

This was due to a new GitHub App feature being tested internally, which was inadvertently enforced for all GitHub-owned applications, including GitHub Mobile.

A mismatch in client and server expectations due to this feature caused logins to fail. We mitigated the incident by disabling the feature flag controlling the feature.

We are working to improve our time to detection and put in place stronger guardrails that reduce impact from internal testing on applications used by all customers.

Resolved - On June 24, 2025 from 09:42 UTC to 12:11 UTC, the Repository UI was degraded for customers using GitHub Enterprise with Data Residency. During this timeframe, the navigational elements on repository pages would not have been visible, impacting roughly 600 users.

The issue was caused by a change that referenced a new resource for this information, which had not yet been configured for the GitHub Enterprise with Data Residency. Additionally, the change had incomplete coverage of the guardrails we employ to prevent these types of exceptions. Due to safe resiliency practices for these elements, the resulting impact was the loss of those elements on the page. A rollback of the impacting change was performed to restore full functionality to these pages.

To prevent future incidents like this, we are investing in additional monitoring for specific errors resulting from these workflows, expanded coverage of end-to-end testing, and alerting when a sharp increase in resilient fallback behavior happens.

Update - We have deployed a mitigation to the affected instances, and telemetry indicates the error is no longer occurring.
Jun 24, 12:27 UTC
Update - A mitigation is in progress of rolling out to the affected instances. We expect customers to see mitigation within the next hour.

Investigating - We are investigating reports of degraded performance for the Repositories UI. We have identified that the navigation bar is missing in GitHub Enterprise Cloud with data residency instances for the repositories related pages and are currently attempting a mitigation.

Resolved - On June 18, 2025 between 22:20 UTC and 23:00 UTC the Claude Sonnet 3.7 and Claude Sonnet 4 models for GitHub Copilot Chat experienced degraded performance. During the impact, some users would receive an immediate error when making a request to a Claude model. This was due to upstream errors with one of our model providers, which have since been resolved. We mitigated the impact by disabling the affected provider endpoints to reduce user impact, redirecting Claude Sonnet requests to additional partners.

We are working to update our incident response playbooks for infrastructure provider outages and improve our monitoring and alerting systems to reduce our time to detection and mitigation of issues like this one in the future.

Jun 18, 23:13 UTC
Update - We are experiencing degraded availability for the Claude 4 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. We recommend using Claude 3.7 as an alternative.
