I think that "good" is all relative to what you are most likely to be
able to reach from wherever your location happens to be!

Google's...  Level 3's.....  Root DNS servers (anycast)....  Pick something.

Hi list.

I'd like to setup my default routes to the Interwebz to be
conditional on
reachability of something on the Interwebz. I got two different ISPs
(no
BGP). I'm trying to figure out what would be a reliable object to
track?
Meaning, it's probably not reasonable to track my ISPs default gateway,
since it does not protect me from someone on the ISP side screwing
up. I'm
thinking of tracking something like google.com, but am not sure if
after I
resolve google.com for the first time, it will be simply tracking an
arbitrary server (or some load balancer).

I wanted to see what experienced folks think is a reliable tracking
target.
Any comments are much appreciated.

Publicly advertised DNS server IPs should be good, such as google's
8.8.8.8
and 8.8.4.4.
