From a cursory glance seems to be ok from where I'm currently looking from
(at&t), then again I haven't done my technical diligence. Will need to look
further and I'm sure someone will pipe up.

Do you have any traceroutes, route stats, etc to give us as to what you are
experiencing?

No, no traceroutes since when I'd query BGP, it just said that the network
didn't exist in the table like :

***route-server***>sho ip bgp 71.74.56.243
% Network not in table
***route-server***>sho ip route 71.74.56.243
% Subnet not in table


(Only output I captured... But I know that Cerfnet did this too.)

Looks like Level3 has trouble in Atlanta.

I'm in Memphis, with servers in Atlanta and Dallas. I'm currently seeing
transit from my residential connection to Atlanta through PCCW instead
of L3. Never would have noticed had I not seen your post, but PCCW is
not my normal route.
