I was having the exact same problem since last Thursday -- I have SBC dsl service too, and I couldn't get on the site and wasn't getting any e-mails. I was so ecstatic yesterday when it was fixed. I had tried everything I could think of, clearing cookings, deleting files, etc. I had actually thought maybe someone had decided they didn't like me here and had asked for my computer to be blocked.

LOL. Glad to know it was just a ISP computer issue.
