I have a constant problem with Orcon where Apple support KB articles like this do not load:
http://support.apple.com/kb/HT1389

The Apple discussions sites load and even support.apple.com loads, but ot the articles.

I try the same link over 3G (voda) and the site works.

Is anyone else having this issue?

(I used to have a lot of performance issues with Orcon but most of them have gone now after a thread a month or two back discussing the issue)
