We are thinking of deploying anycast in our network for our DNS servers and mirrored/redundant customer connection.
Any useful feedback would be appreciated.
It would be a small footprint, 3 sites within the continental US.
see http://www.isc.org/tn/, specifically ISC-TN-2003-1. (as a bonus, this TN was markuped using the recently mentioned tools from xml.resource.org.) f-root works this way. paly/sanfran, san jose, madrid, hong kong, and new york city are all bgp-anycasted. (with plans for several dozen more cities.) as long as you don't make silly assumptions about client locality based on "which anycasted server heard it", such that you give back incoherent answers in hopes that they will be somehow client-optimal, bgp-anycast isn't even controversial at this point in time. -- Paul Vixie
