Description

It seems that a lot of accesses started today from 141.115.102.180 (many requests per second, often) and the service is not able to cope with them.
We can increase the VM resources somewhat, but I fear that it would only slow down the interval between failures.

Closing the ticket. If those accesses were legit, they should rate limit it before removing the firewall rules.
