Discontiguous networks create a supportability problem, and increase
the risk of these very issues. One is not well advised (IMHO) to
create such a network without a darn good reason...and this (to me)
does not seem to be a Darn Good Reason.

That's exactly the point. It is easier to solve this problem (not to
mention scale or plan) for a farm or cluster than for servers in each
of 270 pops. And easier yet when I use names, rather than the silly
"well knowns". 

Opinions aside, the infrastructure required to support stateful load
balancing for these boxes in each of their routing islands is
substantially more than most are committing these days...
