A couple of nodes seem to be really off. Sometimes the CPH node is up at 98% The slow downs happen in multiple browsers both with and without using a proxy/cache. Just right now it is fast and responsive, I'll get a date-time stamp next time it gives problems. Last week there were two days I could not get through at all.

It was really slow at Mon Sep 3 13:29:49 UTC 2012
but mostly it's been improved. That was going to the server 'lingonberry'

Yes I have had this problem. I put it down to congestion on the interwebs :)
When it happens I just go somewhere else.
Sorry but I know this does not help diagnosis.
It looks to me that ae-2-52.edge4.London1.Level3.net node is dropping packets. There probably isn't much the forum can do about it. I monitored it for a time and it seems to be periodic and not constant. I have had to monitor it for 10 minutes to see packet losses fluctuate from 0% to 90%.
It is just an annoyance.
