All the failure modes that ISC has seen with anycast nameserver instances can be avoided (for the authoritative DNS service as a whole) by including one or more non-anycast nameservers in the NS set.
Am I missing something.. So you say: 10.1.0.1 Anycast (x50 boxes) 10.2.0.1 Non-anycast is somehow different from 10.1.0.1 Anycast1 (x50 boxes) 10.2.0.1 Anycast2 (x50 boxes - different to anycast1) In each scenario two systems have to fail to take out any one customer.. but isnt the bottom one better for the usual pro anycast reasons?
