Yep. One other data point, I also demonstrated remote desktop connection
to this person and it was also much slower than expected.  I don't think
it was a PC problem either.  I know it's a small sample, but the way
Qwest's been bundling services and the history of USWest and Qwest
rather poor DNS performance, I wouldn't be surprised at network
congestion upstream of the ATM clouds.

If others aren't seeing it, it could be something else, but if I thought
it was the local loop/PC, I'd have seen different indications.  PC was
clean of ugly processes.

By the number of DSL router reboots needed in Greeley since Tuesday
indicates Qwest has been making some local network or firmware changes.
No reports of this in Fort Collins or Loveland area yet.  This has been
seen at CPE equipment homed to both central offices and a couple of
remote terminals.

Could be localized issue.
