If your GitHub Actions jobs are stuck in "Queued" or waiting for a runner, GitHub has now confirmed there is an incident.

GitHub says they identified an issue with a database primary and are failing over to a replica.

Actions is affected, and GitHub Pages is also experiencing degraded performance.

So if you have been checking your workflow, runner settings, permissions or billing, it might not be your configuration.

Hopefully this saves someone else from spending an hour debugging their YAML.
