I do Anycast for much much smaller. It's great to reboot one server and have the other take all of the load. 0 customer interruption, not even a single DNS query lost.
Hi Josh, You don't need anycast routing to do that, or more precisely you don't need the route to persist in an anycast state for more than a few seconds during the handoff. You can implement dynamic but still unicast routing to the DNS servers without incurring the wrath of the anycast gods. Regards, Bill Herrin -- William Herrin bill@herrin.us https://bill.herrin.us/
