We encountered an issue with config propagation to our builders causing deploys to not turn live. After deploying an update internally to make this configuration availible- queued deploys are now going through. No action is required on your part.

An issue related to a builder configuration is the culprit here. As a result, builds aren't able to progress because it's looking for configuration that isn't fully rolled out. We are kicking the tyres and deploying a fix. Apologies!
