Several Klei Official servers have been periodically crashing at random times.

I haven't had the opportunity to play on a Klei server and not have the server crash at some point for a non-insignificant number of my public sessions.

I am unsure if it is related to the previous instance of griefers intentionally crashing servers, but it always seems to happen a little before the server manages to get everything together for one of the later game bosses, roughly 35-50 days in with sudden massive lag spikes leading to an inevitable crash.

I only use the US based servers since they usually have the best ping, so if you were to check any of their logs check those ones.
