Given that in the ISC case the hostname.bind query can tell you at least the region + instance#, it seems plausible that some system of systems could track current/changes in the mappings, no? and either auto-action some 'fix' (SHUT DOWN THE IAD INSTANCE IT's ROGUE!) or at least log and notify a hi-priority operations fixer.
That sort of capability at the application layer certainly seems prudent to me, noting that it does assume you have a measurement node within the catchment in question and are measuring at a high enough frequency to detect objective incidents.
Given something like the unique-as work Verisign has been behind you'd think monitoring route origins and logging 'interesting' changes could accomplish this as well?
I'm a fan of both routing system && consumer-esque monitoring, and do believe that a discriminator in the routing system associated with globally anycasted prefixes makes this simpler - for both detection, and possibly even reactive or preventative controls IF necessary. A unique origin AS is not the only place you can do this in the routing system, as I'm sure some will observe, but it seems an ideal location to me. -danny
