Having some problems with the Forum

[tinkthank]

In the past two weeks, I have often not been able to load this forum page. Sometimes it loaded, but I have not been able to call up any posts.
Then, a couple of hours later, everything is fine again. Rinse, repeat.
This happens from two different computers in two cities; in Hannover, I use win2000 as a client on our server with a DSL connection and a router; havent had any problems with that. In Berlin, I have a win98SE laptop connected to a DSL modem (D. Telekom), and when I have problems with this forum I have none elsewhere. In Berlin, under Win98, I have a little icon in my task manager thingy at the bottom right of my screen, two little green monitor-looking thingies, and they light up when they are transfering information, and when I wait for one of these forum pages to load they are dark.
Is this a problem with me or a problem with the forum, and can I do anything about it?
Thanks much
