I can't login into my AT&T account
From what I see, there are others who have suffered the same fate. I seem to be stuck in the same cycle that you see in these threads (among others):
It almost seems as if my IP has been tagged as problematic - I use Sonic for my Internet access here in Berkeley, CA with a public facing IP address in the 135.180/16 range. I tried using a VPN to connect to the AT&T site from a 184.23/16 ip range, and presto, everything works!!! If there's a problem emanating from my IP address, I would appreciate being informed of the issue. Otherwise, I don't expect my home IP address to be blocked by your site!
Please let me know how we could resolve this problem.
