    This incident has been resolved. GitHub connectivity from our EU regions was degraded from ~12:45 to 16:15 UTC, affecting checkouts, ghcr.io, and some eu-west job starts. Normal since 16:15. Affected jobs can be re-run.

    Connections to github.com and ghcr.io from our eu-west, eu-central, and us-east regions have returned to normal as of approximately 15:00 UTC, so checkouts are completing at normal speed and login failures to GitHub Container Registry have dropped to baseline levels. We are continuing to monitor, and re-running any jobs that failed during this period should succeed.

    We are seeing evidence that Git Checkouts are also affected by this. We are seeing high TCP retransmit rates into the EU GitHub loadbalancer. Checkouts in the EU West, EU Central, US East regions are affected.

    We are currently observing higher rates of errors for the upstream GHCR registries which may indicate an undeclared GitHub incident. We are currently monitoring.
