Resolved - This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
Sep 17, 17:55 UTC

Update - We have confirmed the original mitigation to failover has resolved the issue causing Codespaces to become unavailable. We are evaluating if there is a path to recover unpushed data from the approximately 2000 Codespaces that are currently in the shutting down state. We will be resolving this incident and will detail the next steps in our public summary.
Sep 17, 17:55 UTC

Update - For Codespaces that were stuck in the shutting down state and have been resumed, we've identified an issue that is causing the contents Codespace to be irrecoverably lost which has impacted approximately 250 Codespaces. We are actively working on a mitigation to prevent any more Codespaces currently in this state from being forced to shut down to prevent the potential data loss.
Sep 17, 16:51 UTC

Update - We're continuing to see improvement with Codespaces that were stuck in in the shutting down state and we anticipate the remaining should self resolve in about an hour.
Sep 17, 16:07 UTC

Update - Some users with Codespaces in West Europe were unable to connect to Codespaces, we have failed over that region and users should be able to create new Codespaces. If a user has a Codespace in a shutting down state, we are still investigating potential fixes and mitigations.

Investigating - We are investigating reports of degraded performance for Codespaces

Update - Git Operations is experiencing degraded performance. We are continuing to investigate.
Sep 16, 18:02 UTC

Update - A recent change to our API routing inadvertently added an authentication requirement to the anonymous route for LFS requests. We're in the process of fixing the change, but in the interim retrying should eventually succeed.

Repository search is degraded

Resolved - This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
Sep 15, 21:01 UTC

Update - Most searchable repositories should again be visible in search results. Up to 1.5% of repositories may still be missing from search results.

Many different actions synchronize the repository state with the search index, so we expect natural recovery for repositories that see more frequent user and API-driven interactions.

A complete index reconciliation is underway to restore stagnant repositories that were deleted from the index. We will update again once we have a clear timeline of when we expect full recovery for those missing search results.
Sep 13, 22:39 UTC

Update - Customers are not seeing repositories they expect to see in search results. We have restored a snapshot of this search index from Fri 12 Sep at 21:00 UTC. Changes made since then will be unavailable while we work to backfill the rest of the search index. Any new changes will be available in near-real time as expected.

Incident with Actions

Resolved - On September 10, 2025 between 13:00 and 14:15 UTC, Actions users experienced failed jobs and run start delays for Ubuntu 24 and Ubuntu 22 jobs on standard runners in private repositories. Additionally, larger runner customers experienced run start delays for runner groups with private networking configured in the eastus2 region. This was due to an outage in an underlying compute service provider in eastus2. 1.06% of Ubuntu 24 jobs and 0.16% of Ubuntu 22 jobs failed during this period. Jobs for larger runners using private networking in the eastus2 region were unable to start for the duration of the incident.

We have identified and are working on improvements in our resilience to single partner region outages for standard runners so impact is reduced in similar scenarios in the future.
Sep 10, 14:02 UTC

Update - Actions hosted runners are taking longer to come online, leading to high wait times or job failures.
Sep 10, 13:31 UTC

Investigating - We are investigating reports of degraded performance for Actions

Degraded REST API success rates for some customers

Resolved - On September 4, 2025 between 15:30 UTC and 20:00 UTC the REST API endpoints git/refs, git/refs/*, and git/matching-refs/* were degraded and returned elevated errors for repositories with reference counts over 22k. On average, the request error rate to these specific endpoints was 0.5%. Overall REST API availability remained 99.9999%. This was due to the introduction of a code change that added latency to reference evaluations and overly affected repositories with many branches, tags, or other references.

We mitigated the incident by reverting the new code.

We are working to improve performance testing and to reduce our time to detection and mitigation of issues like this one in the future.
Sep 4, 20:25 UTC

Update - The deployment has completed and we expect customers who have been impacted to see recovery. We are continuing to monitor.
Sep 4, 20:05 UTC

Update - We are in the process of deploying the PR to revert the change that was causing timeouts to this endpoint. We will update again once that deployment is complete.
Sep 4, 19:28 UTC

Update - We have identified a deployed change that correlates with the increase in 5XX errors to the GitRefs REST API. This is particularly affecting requests for repos with very large numbers of commits. We are working on rolling back this change which we expect will resolve the issue.
Sep 4, 18:57 UTC

Update - API Requests is experiencing degraded performance. We are continuing to investigate.
Sep 4, 18:52 UTC

Update - Customers are experiencing 504 responses for some API requests for regarding repo refs/tags. We are investigating.
