Is Circle CI down?

GitHub is currently experiencing a service degradation (https://www.githubstatus.com/incidents/yjysg0xrl67m). Customers who use GitHub as their VCS may experience impact to their CircleCI platform experience as a result, impacting checkout and workflows. We will provide another update as we have more information to share. Thank you for your patience.

The issue impacting customers who use GitHub as their VCS while GitHub was undergoing a service degradation (https://www.githubstatus.com/incidents/yjysg0xrl67m) has now been resolved. GitHub has resolved the underlying issue and the affected functionality has returned to normal. We thank you for your patience.

We are investigating delays in starting jobs using the gen3 resource class.

We are continuing to investigate elevated wait times affecting customers using gen3 machine executors. Affected jobs may take longer than usual to start. We will provide another update as soon as we have more information to share.

We have identified the issue and are working with our provider to resolve the availability of gen 3 resources. Gen 1 and Gen 2 are both fully operational.

Between 19:24 UTC on 22 July and 01:50 UTC on 23 July, customers using the gen3 preview machine (Linux VM) resource classes experienced delays and, in some cases, jobs failing to start. We have removed the gen3 resource classes while we address stability issues affecting them. Unfortunately, workflows that we were unable to provision compute capacity for during this period were cancelled. Affected customers should change their resource class from gen3 to gen2 and rerun those workflows. We thank you for your patience while our team worked to resolve this.

A subset of customers may have experienced errors loading app.circleci.com starting at 03:18 UTC. A fix has been deployed and we are monitoring for full recovery. Thank you for your patience while our engineers confirm recovery. We will provide another update shortly.

Between 03:18 UTC and 06:04 UTC on July 22, 2026, a subset of customers were unable to access app.circleci.com. The issue has been resolved and access has returned to normal. We thank you for your patience while our team worked on implementing a fix.

We have identified an issue with GitHub API requests that may cause some customers to see workflows stuck in a running state or workflows fail to start. GitHub has reported incidents on the APIs https://www.githubstatus.com/incidents/ph5nns5y4gxj https://www.githubstatus.com/incidents/8vfyvq16hzh9 We are monitoring the stability of GitHub APIs and will update this page as more information is available.

We are also seeing errors processing push event webhooks due to the upstream API outage. Users may need to retry pipelines for these push events.

We are seeing signs of recovery from the GitHub API. We will stay in a monitoring state to verify that the API error rate has recovered.

GitHub API error rates have recovered to normal levels. During the incident, some customers may have seen pipelines fail to start or not receive status updates. Some pipelines may be stuck in a running state. * You should re-push commits or use the UI to manually trigger pipelines that didn't start. * Pipelines in a stuck running state should be canceled and rerun. If you encounter any issues please contact CircleCI support.

## Summary On July 20, 2026 from 00:22 to 01:45 UTC, CircleCI customers using our GitHub integrations experienced failures running pipelines and experienced workflows getting stuck. During this incident, some pipelines triggered by users using GitHub failed to start or ran as error pipelines. Customers whose pipelines failed or ran as error pipelines during this window should re-run them. This was caused by an [upstream API degradation at GitHub](https://www.githubstatus.com/incidents/ph5nns5y4gxj), which impacted many GitHub APIs that CircleCI uses to trigger and run pipelines. By 01:45 UTC, GitHub APIs recovered, and customer pipelines ran normally. The original CircleCI status page can be found [here](https://status.circleci.com/incidents/9lvbbbs9l87b).  ## What Happened \(all times UTC\) Beginning 00:22 on July 20, 2026, GitHub began returning elevated errors for the following API requests: * `applications/*/token` * `repos/*/commits` * `repos/*/*/contents/*` * `repos/*/*/hooks` * `repos/*/*/hooks/*` * `repos/*/*/keys` * `repos/*/*/pulls` * `repos/*/*/statuses/*` CircleCI relies on these requests to correctly trigger and run pipelines. At 00:22, our internal monitoring alerted us to the problem. Our team began investigating, and found that a small number of pipelines belonging to GitHub projects either failed to start or ran as error pipelines. This included scheduled pipelines and workflows. In addition, a small number of customer workflows experienced stuck jobs and required a re-run of the workflow to fix. At 01:45, GitHub recovered and pipeline processing returned to normal operating levels. Only pipelines triggered during the incident window were affected, and customers should re-run those pipelines. ## Future Prevention and Process Improvement We are actively working to improve the resilience of pipeline processing during GitHub service disruptions to reduce the customer impact of similar incidents in the future. We are scoping features that will help customers recover with reduced manual steps after incidents resolve. Customer experience is our top priority, and we commit to continually improving the reliability of our systems to match the trust that our customers place in us. Please reach out to our support team with any questions or concerns.

We're investigating an issue where customers may see errors loading the CircleCI web app and signing in, along with pipelines and scheduled workflows failing to start or running late. This is related to an ongoing incident affecting GitHub. You can follow GitHub's status at https://www.githubstatus.com/incidents/gxycch3076xk. Our engineers are actively investigating. We will provide another update as soon as we have more information to share.

We are continuing to see high failure rates from GitHub APIs which are impacting login and workflow processing. We will continue to monitor the GitHub API for recovery.

What's happening The upstream incident affecting GitHub has been mitigated and is now being monitored on GitHub's side. You can follow GitHub's status at https://www.githubstatus.com/. What can you expect Access to the CircleCI web app, sign-in, and pipeline and workflow processing are returning to normal. You may still see intermittent errors or delayed scheduled pipelines and workflows as systems stabilize. Thank you for your patience while we monitor for full recovery.

An incident affecting GitHub's API caused CircleCI customers to experience errors loading the web app and signing in, along with pipelines and scheduled workflows failing to start or running late. GitHub has resolved the underlying incident (https://www.githubstatus.com/) and all affected functionality has returned to normal. Customers whose jobs or pipelines failed may rerun them. Scheduled pipelines and workflows that were missed during the incident will not run automatically and will need to be re-triggered. We thank you for your patience.
