"One anycast implementation is having trouble, therefore anycast
must be inherently bad" is hardly good logic.
Something I forgot to add to my anycast ramblings the other
evening:
Say one has ns1.domain.tld and ns2.domain.tld both anycasted.
Assuming pods have two machines, set your MEDs[*] such that ns1
prefers server "A" and ns2 prefers server "B". This helps
queries destined for different NSes hit different machines.
[*] Or whatever knob you use.

I don't think gtld-servers.net uses anycast; someone correct me
if I'm wrong. F-root != gtld-servers.net.
