Identified
The hosts are back online, we're back at 100% capacity in the Elite clusters. We're still performing a review to ensure the issue does not happen again and that everything's working as expected.

Update
We moved a couple of stand by machines into the Elite clusters, so builds should go through now but might be a bit slower than usual. We're working with our infrastructure provider to restore all the Elite machines to get back to 100% capacity.

Investigating
Due to a sudden issue with multiple host machines used for the MacOS Elite stacks builds targeting those machines / stacks might be restarted multiple times until a suitable host is found.
We're working on fixing the issue ASAP, sorry for the inconvenience.
