Answer 1

Well, it all depends on the external environment and technical specifications.
In most cases, terminate with a fatal error.
Maybe wait a bit and try to connect again.
Perhaps use a different connection address.
Perhaps there are some other ways to crash start in the application.

Answer 2

abuse in the DC, like what I'm paying for, and you sssssuuuuuu ..... turned off the server.
