Problem with ISP accessing some sites? WTF?
 

This is weird, I have comcast at home and att in my office. One server can't be accessed thru comcast network at least once every week. It just hands there. If I use ATT connection all works fine. Have you ever had problems like that and whats causing it??? cache or some sort of firewall? wtf?

routing issue with the way comcast gets there, when it times out do a tracert, see where the connection stops.

I had a similar problem and after tearing my hair out i discover my wireless router had blocked a few sites without me doing anything so check your router settings is my two cents

Yep, same here.

I have had that same issue a number of times with Charter. Luckily, I have a back up T1 in my office for just such an occasion. :winkwink:
