[A] somewhat cleaner way to do this would be to advertize a less
specific route from the DR location covering the more specific route
of the primary location.  If the primary route is withdrawn, voila ..
traffic starts moving to the less specific route automatically without
you having to scramble at the time of the outage to inject a new
route.
This certainly is easier if it's flexible enough.  (If one desires high
splay across several locations, this approach is lacking.)  The tough
part then becomes internal application consistency.
