Autotester farm is down

[Lodovico Giaretta via Digitalmars-d]

I don't know much about PRs and the autotester, so I'm probably 
wrong, but...
It looks like [1] the autotester farm is down: most hosts have 
been unreachable for more than two hours and a half, as of this 
writing.

This may slow down the PRs, as all FreeBSD and all Windows hosts 
are gone.

Is it known and expected (maybe maintainance)?
