Deploys failing at release stage with 504

We’ve tried both local and remote deploys, but both end with the same message:

==> Creating release
Error server returned a non-200 status code: 504

I’ve seen this intermittently before but it usually goes away. This time it seems to be a sustained issue. Anyone else seeing this?

This happens when requests to the Fly API time out, for one reason or another. Usually, it should be intermittent. Are you still seeing this?
