Repeated packet loss on AT&T

[Donald Stahl <don () calis blacksun org>]

I have a cage at an AT&T hosting facility in NY.

Every few weeks I end up with horrendous VPN problems to another site I 
have on MCI's network in Maryland, as well as to a partners site, in the 
same area, also on MCI.

mtr -s 800 to either site shows 10% packet loss on the hop from:
12.122.105.45 -> 192.205.34.50

Both of these appear to be AT&T routers (I say appear to be because 
I am relying on the netblock information from ARIN- reverse DNS for 
routers seems to be uncool).

Does anyone else run into this problem? Smaller pings show far fewer 
(if any) issues and other traffic is passable- but it kills my VPN's.
