My phone goes out every time it rains.

Well they aren't blocking anything, there's been many reports of trouble accessing the websites.  Most likely the only other providers would be cable companies, if you have access, and they would also require internet.  There's also resellers, again if in your area, but they would use the same facilities as AT&T.  Your other option would be a wireless home phone from one of the major cell phone carriers.  You could escalate your issue by filling out the following Customer care executive contact and there's also filing an FCC complaint.  As far as reporting you'll have to call if you can't access the site, you might want to clear your cache first to see if that's the problem. 

That customer care link just puts me back to the repair.com which is the one that is blocked.  Get a Forbidden error.  But thanks for responding.  Guess I will have to cut the ATT cord and go with someone else.  Too bad.   Been with ATT all my life.  But I am through with their "we are too big to fail" attitude.

I have the same issue. However, now my landline goes out almost everyday lately. Now when I try to submit a trouble ticket, it says the site is "FORBIDDEN". I've cleared cookies on the site and still can't submit a ticket. 

Same here every time it rains my landline stops working, and the website for ATT.Repair for a ticket doesn't work.  It's soo frustrating.
