I have Verizon Yahoo mail. I began seeing this message tonight. I spoke to Verizon Tech support and they said- yes, it is a widespread issue and it has to be fixed by Yahoo.
Has anyone else been getting this message?
I noticed this yesterday mid-morning. Going on 24 hours of not being able to access my Yahoo email account. I'm livid. I just find this completely unacceptable and can't figure out how to contact Yahoo to find out when this will be fixed.
