On the subject of helpdesks - for years I have wished that ISPs would have two different types of helpdesk; one for n00bs, and one for people with a clue. That way when you (as an IT professional) ring the ISP you can talk to someone who actually knows what you are talking about.
Slightly OT: But Stroke, some of the worst calls i've ever dealt with have been from so called "it professionals" who think they actually know whats going on when in fact they've missed a couple of basic steps and gone through every advanced step. I know more helpdesk techs that cringe when they hear "I'm a professional" as opposed to a 90 year old calling saying "whats an internet?"
On topic: Sounds like congestion, looks like congestion, but obviously not congestion since they don't want to use that term. :) But at least it sounds like they're doing upgrades that should sort it out in due time Burger.
