This actually points out a potential improvement in the AS112 setup. As
people have pointed out, BGP will result in sub-optimal routing often
enough. Since all AS112 servers advertise from the same /24, there's
not much that can be done to improve the situation.

However, perhaps we could persuade IANA to delegate this to a set of 4
or 5 addresses in different subnets, and then each AS112 operator could
pick one of these to advertise. It could in principle decrease the
amount of cross-oceanic traffic, because as you noted DNS will
automatically try to get to the server that responds fastest.

I know it's a bit weird to be thinking about optimizing network load
and user response for a server who's whole job is to say "nothing to
see here", but there you go. :)
