[BBLISA] need a BGP tunnel peer (was Re: comcast ... again)

[Dean Anderson]

Tunneling to another ISP isn't going to be very efficient.  You are down
if they are down, or if anything in between you and them is down; then
you have ordinary problems if anything in between them and the client is
down. (that was severe enough to motivate the search for multihoming)

BGP flapping can make things worse on both connections.

Why not just get a /24 from VZ and dual home your DNS, mail, etc servers
to different IP addresses?  Seems easier.
