This incident has been resolved.

A fix has been implemented and the backlog of jobs is draining. We will continue to monitor until the issue is fully resolved. We have also temporarily provisioned additional rendering resources to help work off the backlog of jobs more quickly for the customers affected. Thank you for your patience as we work to resolve this issue.

We have identified an issue with an internal job processing system that is causing a backlog of rendering jobs, so some builds are not processing as quickly as expected. We are working on a fix and will update this when it is in place.
