I just had my Yahoo, Verizon, and Facebook attacked, along with my wife's Verizon, and Facebook. I had to call Verizon to get my acct restored, made several attempts on Yahoo before getting that, THEN once Verizon was restored I was able to get Facebook back online. You'll probably have to send a password reset which will send a request to your secondary acct you used as backup.
