Disruption with some GitHub services

Resolved - Between 06:04 UTC to 10:55 UTC on August 1, 2025, 100% of users attempting to sign up with an email and password experienced errors. Social signup was not affected. Once the problem became clear, the offending code was identified and a change was deployed to resolve the issue. We are adding additional monitoring to our sign-up process to improve our time to detection.

Increase in 429s for Git Operations

Resolved - Public Summary Draft
Between July 28, 2025 16:31 UTC to July 29, 2025 12:05 UTC users saw degraded Git Operations for raw file downloads. On average, the error rate was .005%, with a peak error rate of 3.89%. This was due to a sustained increase in unauthenticated repository traffic.

We mitigated the incident by applying regional rate limiting, rolling back a service that was unable to scale with the additional traffic, and addressed a bug that impacted the caching of raw requests. Additionally, we horizontally scaled several dependencies of the service to appropriately handle the increase in traffic.

We are working on improving our time to detection and have implemented controls to prevent similar incidents in future.
Jul 29, 12:05 UTC

Update - Continued monitoring is showing that impact has been mitigated and normal service operation has been restored.

We are going to resolve the incident at this time. Thank you for your patience as we investigated this problem.
Jul 29, 12:05 UTC

Update - We identified and removed unhealthy hosts from our system. This has led to a reduction of 429s and a return to normal operating conditions.

We are continuing to monitor recovery and will resolve the incident once we are confident the impact has been mitigated.
Jul 29, 11:32 UTC

Update - We are seeing an increase in 429s when retrieving git artifacts from GitHub.com. This is manifesting in many ways, for example, in failed GitHub Actions workflow runs.

We have our engineers working on mitigation and we will provide more information as we have it. Thank you for your patience.

GitHub Enterprise Importer migrations are stalled

Resolved - Between approximately 21:41 UTC July 28th and 03:15 UTC July 29th, GitHub Enterprise Importer (GEI) operated in a degraded state where migrations could not be processed.

Our investigation found that a component of the GEI infrastructure had been improperly taken out of service and could not be restored to its previous configuration.
This necessitated the provisioning of new resources to resolve the incident.

As a result, customers will need to add our new IP range to the following IP allow lists, if enabled:
- The IP allow list on your destination GitHub.com organization or enterprise
- If you're running migrations from GitHub.com, the IP allow list on your source GitHub.com organization or enterprise
- If you're running migrations from a GitHub Enterprise Server, Bitbucket Server or Bitbucket Data Center instance, the allow list on your configured Azure Blob Storage or -- Amazon S3 storage account
- If you're running migrations from Azure DevOps, the allow list on your Azure DevOps organization

The new GEI IP ranges for inclusion in applicable IP allow lists are:
- 20.99.172.64/28
- 135.234.59.224/28

The following IP ranges are no longer used by GEI and can be removed from all applicable IP allow lists:
- 40.71.233.224/28
- 20.125.12.8/29

Users who have run migrations using GitHub Enterprise Importer in the past 90 days will receive email alerts about this change.
Jul 29, 03:15 UTC

Update - This incident is resolved, we will follow up with a detailed root cause analysis as soon as possible.

As part of mitigation, some existing IP ranges were replaced. Migrations with customer owned storage that have IP allow lists enabled will require adding new IP ranges to your IP allow lists to prevent migrations from failing.
- 20.99.172.64/28
- 135.234.59.224/28

Incident with Issues, API Requests and Pull Requests

Resolved - Between July 28, 2025, 22:23:00 UTC and July 29, 2025 02:06:00 UTC, GitHub experienced degraded performance across multiple services including API, Issues, GraphQL and Pull Requests. During this time, approximately 4% of Web and API requests resulted in 500 errors.

This incident was caused by DNS resolution failure while decommissioning infrastructure hosts. We resolved the incident by removing references to the stale hosts.

We are working to improve our host replacement process by correcting our automatic host ejection behavior and by ensuring configuration is updated before hosts are decommissioned. This will prevent similar issues in the future.

Incident with Actions Hosted Runners

Resolved - On July 23rd, 2025, from approximately 14:30 to 16:30 UTC, GitHub Actions experienced delayed job starts for workflows in private repos using Ubuntu-24 standard hosted runners. This was due to resource provisioning failures in one of our datacenter regions. During this period, approximately 2% of Ubuntu-24 hosted runner jobs on private repos were delayed. Other hosted runners, self-hosted runners, and public repo workflows were unaffected.

To mitigate the issue, additional worker capacity was added from a different datacenter region at 15:35 UTC and further increased at 16:00 UTC. By 16:30 UTC, job queues were healthy and service was operating normally. Since the incident, we have deployed changes to improve how regional health is accounted for when allocating new runners, and we are investigating further improvements to our automated capacity scaling logic and manual overrides to prevent a recurrence.
Jul 23, 16:30 UTC

Update - We are applying mitigations to increase Actions Hosted Runners capacity, and are starting to see recovery. We’re monitoring to ensure continued stability.
Jul 23, 16:11 UTC

Update - We're investigating delays provisioning Actions Hosted Runners. Customers may see delays over 5 minutes for jobs starting.
