Incident with GraphQL API Requests

Resolved - On August 11, 2026, between 14:00 UTC and 16:00 UTC the GraphQL API service was degraded and customers in saw higher than normal timeouts. On average, the timeout rate was 0.06% and peaked at 0.14% of requests routing to the service.

This was due to increased utilization at one of our sites which caused resource contention across our dependencies, leading to an increase in timeouts for GraphQL requests. We mitigated the incident by increasing capacity to alleviate the capacity bottleneck.

We are working to improve our monitoring so that we can proactively reduce the impact of high consumption requests in addition to scaling up; Additionally, we will improve our time to detection and mitigation of issues like this one in the future.

Disruption with creation of fine grained personal access tokens

Resolved - On August 10, 2026, between 17:16 and 18:21 UTC, users were unable to create new fine-grained personal access tokens (FG PAT) through the GitHub website. When a user submitted the FG PAT creation form, they were returned to the FG PAT list without an error message and no FG PAT was created. Creating classic personal access tokens, as well as editing or deleting existing FG PAT were not affected.

The cause was a change to how the website loads certain front-end JavaScript that was enabled for all users at 17:15 UTC; the change interacted with an issue in the token creation form's confirmation step that prevented it from running, so the final submission that actually creates the token never completed. Because the page still loaded and the server returned a normal response, the failure produced no error message. GitHub mitigated the incident by disabling the change at 18:21 UTC, at which point token creation recovered immediately, and the incident was resolved at 18:46 UTC.

To reduce the chance of recurrence, GitHub is adding monitoring and alerting for anomalies in the FG PAT creation success rate and is removing the issue in the FG PAT creation form that prevented the confirmation step from running. GitHub is also adding automated detection of the issue so other areas of the GitHub front end do not repeat the problem.
Aug 10, 18:46 UTC

Update - We identified the source of the issue affecting creation of fine-grained personal access tokens and have applied a mitigation. Users should now be able to create new fine-grained tokens successfully. We are continuing to monitor to confirm full recovery.

Incident with Actions

Resolved - On August 6, 2026, between 15:05 UTC and 00:14 UTC on August 7, GitHub Actions experienced degraded availability. During the incident, workflow runs failed or remained queued for an extended period of time. Customers using both GitHub-hosted and self-hosted runners were affected. At peak, 71% of workflow runs experienced infrastructure failures and 75% of the remaining workflow runs were delayed by more than 5 minutes.

The incident was triggered by a routine deployment to an internal Actions service responsible for processing events and generating Actions jobs. The deployment exposed an existing capacity and concurrency weakness. As pods were replaced during the deployment, remaining capacity became saturated, causing services to crash and triggering a cascading impact across multiple clusters and downstream services.

These services recovered at 17:00 after expanding capacity, throttling incoming webhook-triggered work to allow the system to recover, and increasing processing capacity for the backlog of affected events.

As the incident progressed, a backlog of work accumulated across the systems responsible for assigning jobs to runners. Due to a latent bug in one of the services responsible for job assignment, runners were getting assigned jobs that were no longer valid and then getting stuck retrying those jobs, preventing them from picking up valid work.

This second stage of impact was mitigated by deploying changes to prevent runners from repeatedly attempting to acquire invalid jobs. These mitigations allowed the accumulated queues to drain and Actions to recover to normal operation.

Some Actions Runner Controller (ARC) runners remained stuck after the incident. A mitigation deployed during the incident inadvertently affected these runners, causing some to remain offline until they were manually recovered. We subsequently rolled back the change and are adding automatic recovery in upcoming Runner and ARC releases.

Some jobs created during the incident were also left stuck unable to be retried or canceled. CLI and UI solutions for customers to address these were shared at https://github.com/orgs/community/discussions/204152#discussioncomment-17946043.

To prevent recurrence, we are making improvements to deployment and capacity safeguards for the affected services, strengthening monitoring for the conditions that preceded the incident, improving the resiliency and recovery of queued work and runner assignment, and adding automatic recovery for self-hosted runners affected by similar failure conditions. We are also making additional improvements to reduce the risk of cascading failures and accelerate recovery during large-scale Actions disruptions.
Aug 7, 02:04 UTC

Update - During the incident, some Actions Runner Controller (ARC) runner pods became stuck in an idle state. Affected users can delete those pods using kubectl or redeploy their Actions Runner Controller application. ARC will automatically create replacement runners.

The next releases of Actions Runner and Actions Runner Controller will include an automatic recovery mechanism, preventing the need for these manual steps in the future.

Some workflow-triggering events, including push and pull request events, were not processed during the incident and cannot be replayed automatically. Customers may need to repeat the triggering action by pushing a new commit, updating the pull request, or manually re-running the workflow where applicable.
Aug 7, 02:03 UTC

Update - We’re investigating reports that some Actions Runner Controller runners are taking longer than expected to recover. We’ll provide an update as our investigation progresses.

Aug 7, 00:01 UTC

Update - We have deployed fixes that address runners being assigned invalid jobs and are taking additional steps to clear the backlog of affected jobs. Job completion rates for running workflows have improved significantly, with success rates now at 99%. Global queues for hosted runner assignment are nearly burned down and concurrency queues for customers are being processed. Another change was deployed to accelerate processing the backlog of job requests.

We are gradually restoring throughput for webhook-triggered Actions workflows and monitoring system stability. We have deployed a fix for self-hosted runners that were not picking up jobs and are enabling it incrementally.

GitHub Pages, Copilot code review, and Copilot coding agent may still experience intermittent failures or delays. Migrations using GitHub Enterprise Importer remain paused.

We continue to monitor recovery across all affected services and will provide another update as conditions improve.
Aug 6, 23:13 UTC

Update - We continue to make progress on the issue affecting GitHub Actions. We have deployed a fix that addresses runners being assigned jobs that are no longer valid, and are seeing improvement in job completion rates. For workflow runs that are starting, success rates have increased significantly and are now at 97%. Standard and larger runners are now draining queued work. A change is also in progress to mitigate issues with existing self-hosted runners that are not picking up jobs.

Webhook triggers remain throttled to support recovery. Many push and pull request events are not yet triggering new workflow runs, and we are working to safely restore full throughput.

GitHub Pages, Copilot code review, and Copilot coding agent may still experience failures or delays. Migrations using GitHub Enterprise Importer remain paused.

We are continuing to monitor recovery and will provide another update as conditions improve.
Aug 6, 22:18 UTC

Update - We are continuing to work on an issue affecting GitHub Actions. Webhook triggers remain throttled to aid recovery, so many push and pull request events are not triggering new workflow runs.

We identified runners being assigned jobs that are no longer valid and are deploying a change to address this issue. Both GitHub-hosted and self-hosted runners are affected.

Copilot code review, Copilot coding agent, and GitHub Pages may experience failures or delays. Migrations using GitHub Enterprise Importer have been paused to support mitigation efforts.
Aug 6, 21:30 UTC

Update - We are continuing to work on an issue affecting GitHub Actions. Webhook triggers are currently throttled to help with recovery and and we are processing approximately 15% of webhooks, so many events such as pushes and pull requests are not triggering workflow runs. Of jobs queued, approximately 65% are succeeding, improved from a low of 30 to 40% earlier in this incident.

We have narrowed the remaining impact to runners that are stuck retrying jobs that are no longer available. Both GitHub-hosted and self-hosted runners are affected, and we are working to recover them.

Copilot code review, Copilot coding agent, and migrations using GitHub Enterprise Importer may also be affected.
Aug 6, 20:34 UTC

Incident with Pages - Deployment Lag

Resolved - On August 6, 2026, at 07:00 UTC, a configuration change inadvertently reduced the capacity of the service that processes GitHub Pages deployments. As traffic increased over the following hours, latency in the deployment pipeline progressively increased.

At 12:09 UTC, latency crossed the alerting threshold and the team began investigating. We reverted the invalid configuration and applied additional mitigations, including reducing status deployment processing to lower the load on our Redis cluster. Latency returned to normal levels at 15:40 UTC.

Customer impact occurred from 11:34 to 15:32 UTC. During this period, we failed to process approximately 128,000 deployments.

We have updated our alerts to detect elevated processing latency sooner and to notify us immediately when latency causes deployment processing failures. We've confirmed this incident was not fully captured by our availability metrics. In the coming days, we'll update how GitHub Pages availability is measured so incidents like this are accurately reflected going forward.

Some Copilot Cloud Agent jobs not starting

Resolved - On August 5, 2026, between 11:02 and 11:54 UTC, the GitHub Copilot cloud agent service was degraded and new cloud agent jobs were delayed from starting. During this period 100% of newly submitted agent jobs were affected. The incident was limited to delay of cloud agent jobs. No jobs were lost and the queued backlog was processed by 13:00 UTC. This was due to an internal rate limit used to protect service availability that was enabled more broadly than intended delaying more traffic than expected.

The service recovered when the rate limit window expired. We then tuned the control so it no longer affected unrelated coding agent traffic.

We are working to improve the control's scoping and our monitoring and alerting to reduce our time to detection and mitigation of similar issues in the future.

Incident with Copilot

Resolved - On 2026-08-03, between 06:52 and 11:25 UTC, some GitHub Copilot users experienced errors when using chat and agent features. Requests to list the available models failed, and because every chat or agent interaction begins by retrieving the list of models, affected users saw their requests fail. On average about 3% of these model-listing requests failed during the incident (roughly 97% succeeded), but failures were significantly higher during peak-traffic periods, at times approaching 100% for the affected internal lookups. Approximately 4,066 users were affected in a single 60-minute window, concentrated among IDE-based clients. The underlying AI models themselves remained healthy throughout.

The incident was caused by an increase in how often clients requested the model list, which pushed an internal user-authorization lookup past a rate limit; the rate-limited responses were surfaced to users as errors. We mitigated the impact by increasing how long Copilot caches that authorization lookup, which reduced load on the internal service, and we have additional capacity and rate-limit changes in progress. To prevent recurrence we are improving monitoring for this class of failure, adjusting cache and rate-limit settings, and coordinating with client teams on request patterns.
