Hmm ...

ssh: connect to host gitmaster.postgresql.org port 22: Network is unreachable

Maybe that's just me, but it's happening through two different ISPs.

I tried flushing local nameserver cache, but it doesn't seem that
gemulon's IP address has changed (I still see 72.32.157.198).
Should it have?

Yeah, now my ssh is complaining about the address change, but I see
it's still the same server key, so all good.
