## Updates from GitHub
### 2026-07-20 00:25 UTC: investigating
We are investigating reports of impacted performance for some GitHub services.

### 2026-07-20 00:25 UTC: monitoring
Some Git LFS operations, and loading files through the API are failing. We are investigating.

Some Git LFS operations, and loading files through the API are failing. We are investigating.

### 2026-07-20 01:15 UTC: investigating
The Git LFS API issues have been identified as being related to a separate incident where Actions is experiencing degraded availability. We’re consolidating our investigation efforts under that incident.

### 2026-07-20 01:45 UTC: investigating
Git LFS API success rates have returned to normal. We will continue to monitor the service closely.

### 2026-07-20 01:46 UTC: resolved
Between July 19, 2026, at 23:05 UTC and July 20, 2026, at 03:55 UTC, Actions self-hosted and larger runners were unable to connect to GitHub. During this period, Actions jobs were delayed or failed when trying to acquire a runner. Jobs using standard and Mac hosted runners were not affected. Reconnection traffic from affected runners also increased load on GitHub APIs, resulting in 3-4 seconds of additional average request latency and elevated 5xx error rates.
The incident was caused by a certificate lifecycle management failure in a subset of internal services, resulting in an SSL certificate expiration that disrupted runner connectivity. We restored service by rotating the affected certificate. Recovery began at 02:45 UTC. By 03:55 UTC, queued workflow backlog had been processed and workflow delay rates returned to normal.
To prevent recurrence, we are strengthening certificate renewal automation, adding fallback expiry monitoring and alerting, and improving circuit-breaker protections during runner API disruptions to reduce the risk of cascading impact to other APIs.
