Hello, on Saturday the 24th of August one of the node, where
the hosted compilers run, failed.
The good thing is that it was automatically replaced and most
of the applications deployed were unaffected, the bad thing
was that the compiler proxy failed to restart
(due to a dependent service not being available at the time)
The service was offline for most of the day but it was restored
Saturday evening and it is working fine now, you can monitor the
status of the applications in the status page.
