On July 8th, 2024, between 18:18 UTC and 19:11 UTC, various services relying on static assets were degraded, including user uploaded content on github.com, access to docs.github.com and Pages sites, and downloads of Release assets and Packages.
The outage primarily affected users in the vicinity of New York City, USA, due to a local CDN disruption.
Service was restored without our intervention.
We are working to improve our external monitoring, which failed to detect the issue and will be evaluating a backup mechanism to keep critical services available, such as being able to load assets on GitHub.com, in the event of an outage with our CDN.

On July 5, 2024, between 16:31 UTC and 18:08 UTC, the Webhooks service was degraded, with customer impact of delays to all webhook delivery. On average, delivery delays were 24 minutes, with a maximum of 71 minutes. This was caused by a configuration change to the Webhooks service, which led to unauthenticated requests sent to the background job cluster. The configuration error was repaired and re-deploying the service solved the issue. However, this created a thundering herd effect which overloaded the background job queue cluster which put its API layer at max capacity, resulting in timeouts for other job clients, which presented as increased latency for API calls.
Shortly after resolving the authentication misconfiguration, we had a separate issue in the background job processing service where health probes were failing, leading to reduced capacity in the background job API layer which magnified the effects of the thundering herd. From 18:21 UTC to 21:14 UTC, Actions runs on PRs experienced approximately 2 minutes delay and maximum of 12 minutes delay. A deployment of the background job processing service remediated the issue.
To reduce our time to detection, we have streamlined our dashboards and added alerting for this specific runtime behavior. Additionally, we are working to reduce the blast radius of background job incidents through better workload isolation.

On July 3, 2024, between 1:34 PM UTC and 4:42 PM UTC the GitHub documentation was degraded and showed a 500 on non-cached pages. On average, the error rate was 2-5% and peaked at 5% of requests to the service. This was due to an observability misconfiguration. We mitigated the incident by updating the observability configuration and redeploying. We are working to reduce our time to detection and mitigation of issues like this one in the future.

On June 28th, 2024, at 16:06 UTC, a backend update by GitHub triggered a significant number of long-running Organization membership update jobs in our job processing system. The job queue depth rose as these update jobs consumed most of our job worker capacity. This resulted in delays for other jobs across services such as Pull Requests and PR-related Actions workflows. We mitigated the impact to Pull Requests and Actions at 19:32 UTC by pausing all Organization membership update jobs. We deployed a code change at 22:30 UTC to skip over the jobs queued by the backend change and re-enabled Organization membership update jobs. We restored the Organization membership update functionality at 22:52 UTC, including all membership changes queued during the incident.
During the incident, about 15% of Action workflow runs experienced a delay of more than five minutes. In addition, Pull Requests had delays in determining merge eligibility and starting associated Action workflows for the duration of the incident. Organization membership updates saw delays for upwards of five hours.
To prevent a similar event in the future from impacting our users, we are working to: improve our job management system to better manage our job worker capacity; add more precise monitoring for job delays; and strengthen our testing practices to prevent future recurrences.
