Incident with Issues and Pages

Resolved - 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.

Incident with Webhooks and Actions

Resolved - 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.

Jul 5, 20:57 UTC

Update - We are seeing recovery in Actions start times and are observing for any further impact.
Jul 5, 20:44 UTC

Update - We are still seeing about 5% of Actions runs taking longer than 5 minutes to start. We are scaling and shifting resources to encourage recovery of the problem.
Jul 5, 20:32 UTC

Update - We are still seeing about 5% of Actions runs taking longer than 5 minutes to start. We are evaluating mitigations to increase capacity to decrease latency.
Jul 5, 19:58 UTC

Update - We are seeing about 5% of Actions runs not starting within 5 minutes. We are continuing investigation.
Jul 5, 19:19 UTC

Update - We have seen recovery of Actions run delays. Keeping the incident open to monitor for full recovery.
Jul 5, 18:40 UTC

Update - Webhooks is operating normally.
Jul 5, 18:10 UTC

Update - We are seeing delays in Actions runs due to the recovery with webhook deliveries. We expect this to resolve with the recovery of webhooks.
Jul 5, 18:09 UTC

Update - Actions is experiencing degraded performance. We are continuing to investigate.
Jul 5, 18:07 UTC

Update - We are seeing recovery as webhooks are being delivered again. We are burning down our queue of events. No events have been lost. New webhook deliveries will be delayed while this process recovers.

Disruption with GitHub Docs

Resolved - 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.
Jul 3, 16:40 UTC

Update - Mitigation measures have been rolled out and we're seeing errors disappear in our telemetry. We'll continue to monitor our services closely to ensure the docs site is fully healthy.
