"Your server denies access to this url"

I get these results quite often. Most recently it has been bass pro. A toll-free call to them and the kind "rep." says there is no problem but she also says her system is down right then and she cannot help with an order. The various website validity checking sites also show "access denied" type messaging.

Then there is the leverguns community site which seldom works but actually seems to be accessible right now though it is slow and I haven't been able to login.

Your thoughts ?
