Monitoring
The issue is now fixed, but we're still monitoring the system. A couple of builds might got stuck in "building" state when the network connectivity was lost - those should clear out automatically in about an hour, or you can manually abort the build & start a new one; new builds should run as expected now.

Update
Network connection seems to be stable now, builds are starting and running correctly, our servers are going through the build queue, which might cause builds to not start immediately.

Update
The network issue seems to be recovering slowly, but it's still not stable. This might cause builds to abort, we're terribly sorry for the inconvenience.
