DNS Servers

Is there anybody out there who is seeing that their DNS servers are
going in and out of operation? We have 5 DNS servers, the service, not
the server, is available/not-available/available. Am I imagining things
or is something funky happening?

hello list,

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.

thanks

See archives. Several people have had good results.

Do you have a specific question? It's pretty simple. Quite a few of us
have done it many times, now.

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.
