I noticed just a little while ago that we're having a lot of DNS fail.
Initial findings were that several of the root-servers we were trying to
reach via our TWTelecom link were unreachable after 2 hops into TWT.

For instance, a.root-servers.net is pingable from a rackspace server, but
not from our network (unless I shut off TWT, at which point it is, but
it's apparently not the same a.root-servers.net instance rackspace sees).
I assume this is one of the root-servers being anycast.
Shutting off our BGP with TWT didn't appear to help (though the
root-servers became reachable)...so I assume there's more going on than
just TWT routing fail.
