I've reported a few problems as an ATT Broadband customer, and gotten
nowhere. From the cable modem at my house, a traceroute to www.uu.net
goes through a router that introduces a 400ms minimum delay. Traces to
ftp.uu.net, in a different netblock, don't incur that delay. It appears
there's a problem between these two, and it affects only some netblocks
and not others.
