This connection uses a Cisco 827 ADSL router and has several static IPs. All IPs show identical delays. Using other circuits between the same two locations, we do not see any delays.
What's the weather like? ;-)

See if you can get the ADSL router to give you upstream/downstream noise margins and any other userful reporting ...
