Why Can't Certain ISP's access my sites?
I'm got a largish php reseller account.I have a rather large problem. It appears that the ISP users of BT Broadband and Freeserve are having big problems accessing our sites. 25% of the time they can. The other 75% of the time they can't. The error they get is Gateway timeout or DNS error.
Now, I'm a bit of a newcomer in this area, and your lot's knowledge far supasses my humble own. Any idea what the problem could be?
