Larger hosted runners experiencing delays

Final update

On November 11, 2025, between 16:28 UTC and 20:54 UTC, GitHub Actions larger hosted runners experienced degraded performance, with 0.4% of overall workflow runs and 8.8% of larger hosted runner jobs failing to start within 5 minutes. The majority of impact was mitigated by 18:44, with a small tail of organizations taking longer to recover. The impact was caused by the same database infrastructure issue that caused similar larger hosted runner performance degradation on October 23rd, 2025. In this case, it was triggered by a brief infrastructure event in this incident rather than a database change. Through this incident, we identified and implemented a better solution for both prevention and faster mitigation. In addition to this, a durable solution for the underlying database issue is rolling out soon.
