So who replaced Intermedia's routers with a lump of cheese? :

Personally, I'm still trying to figure out why Exodus, in all their
apparent wisdom (or lack thereof), has stopped using the GBLX OC-48's in
the former GlobalCenter facilities (or at least SNV3), and is now
shuttling all its traffic out a single Exodus OC-12.  Prior to yesterday
these traces would've shown gblx.net routers (on different IPs), and would
never have touched an exodus backbone...

Of course, this is probably a move I should've expected from Exodus, after
the mongolian flustercluck that was the AS change in SNV3.  You'd think
they would do something like that carefully, as you can -seriously- bone
customers.  But noooooo.  One of our junior admins made the change (since
I was out of town, but hey, it's cut and paste!).  He, and all of the
other affected customers in SNV3 on the conference call, were left on hold
for about half an hour (plus the call started half an hour late),
whereupon the exodus engineering team popped back in and said "We're done
with our side, you guys go ahead!".

Now.  Does it seem logical to kill connectivity over BOTH of your hosting
routers at once, thus killing every single BGP-running customer you have
that isn't physically in their cage at the time?  Or would it seem better
to do what I assumed they'd do, which is do one router, wait for everyone
to make changes, then do the other?

I guess this is what happens when I assume intelligence at a
hosting/backbone provider.
