With an anycast setup using the same IP addresses in every location, returning SERVFAIL doesn't have the same effect, however, because failing over from anycast address 1 to anycast address 2 is likely to be routed to the same pop location, where the same result will occur.
That's why that is a bad idea. Alternative name servers with different IP addresses should be provided at separate locations. Masataka Ohta
