Snapcraft.io builders not working right now

Today, builds at https://snapcraft.io/ are failing for me early and without logs.

Nothing interesting changed on my end. But all architectures are now failing in under a minute, without links to a log to explain why.

Building locally seems fine.

Is this a widespread issue? Or is something wrong with my setup? This is the deja-dup snap, in case that matters.

This is a known issue and the relevant folks are aware and working on it.

This appears to be fixed.
