Build Service is fully functional again, but it will take a while to work through the builds that have been queued during the downtime. Thus, build times will be significantly longer than usual.

The issue was found and a fix has been deployed. New builds go through, but builds made during the outage are still stuck. We are working to fix the issue with the already queued builds as well.

Builds are getting stuck in "created" state. We are looking into the issue.
