The maintenance has been extended again... 12 a.m. Eastern/9 p.m. Pacific is the latest word.
Update: PSN maintenance is requiring more time than expected, and is now expected to complete tonight. We apologize for the inconvenience.— PlayStation (@PlayStation) January 18, 2013
And... it just officially slipped again: 5 am eastern / 2 pacific:
I couldn't get online last night when I tried either, despite being the last account logged in on my console.
I can log in to my main account and my secondary account. I cannot log on to my sons account at all. Tonight was the first time I could log into the PSN for some odd reason, so I haven't been able to comment at all. In addition I cannot send from any account. That sort of sucks, but it is no where as bad as last year!!
