More forum troubles?

I've not seen any other complaints about this, but I've noticed that alongside the well documented automated random logout random feature, there is a large tendency for these fora to grind to a halt unexpectedly.

Pages don't update, forms don't post, and often I try and access it and get a "Page not found" error from my ISP (Virgin).

What is peculiar about this that I experience this problem on both my regularly used machines - one Fedora one XP, and other sites are unaffected so it does seem unique to these fora. I also experience it regardless of browser, Opera, Chrome, Firefox 3.6 and Firefox 4.

Is anyone experiencing similar issues?

Yup, both at work (using proxy) and at home (no proxy)
