we have an UBB hosted at aplushosting.com for a month or so. Our ISP must have done something after they noticed that our board cosumes more than allowed bandwidth. Now our board is soooo slow

But the mystery is that if I connect over modem then the speed is acceptable, but when I go with my company's LAN T1 the ultimatebb.cgi page takes 10 times longer
Can anyone explain this? Many thanks in advance!
Ps. It seems to have problem with CGI files only. Another files such zip etc. are still downloadable quickly 80KB/s
