I guess that you are the only one, who observes and experiences this kind of problem right now, PPPrNe runs on lightning speed presently....
There may be several problems, one, as RadarContact said, may be a proxy you use.
Another one may be the DNS translation. Which browser are you using, is your history (temp internet folders) consuming a lot of space on the harddrive, is there space left on the harddrive for temporary files, does this problem happen on other sites you visit?
As mentioned on othere threads, check the speed of your modem, there may be a problem there.
What OS are you using....
