Most likely you are using a proxy server, which has a problem with this particular page. Perhaps the stored copy has gone corrupt?
If you have a proxy set manually, try to remove it from the browser setting. If you are able to control the proxy, try to flush the cache. If you are automatically redirected to a proxy server beyond your control, there is nothing much to do except wait until the proxy flushes the page by itself...
Well, I do have satellite broadband which uses a proxy server, but beyond that I'm in over my head. Since you seem to think it will eventually sort itself out, I'll try to ignore.
Thanks for your help mwillberg, whatever your first name is.
