My current hypothesis is that Ubuntu automatic security updates (or
something else stupid) somehow activated some sort of overly aggressive
firewall rules, since I ran into the same problem on four other servers I
have running ubuntu with automatic security updates (I ink).  Anyway, the
machines are now way too secure!    I'll find out soon enough though (I
should have this fixed in about two hours).

If you are good at using Dell iDrac remote management with Linux, please
email me...
