I haven't been able to sign in for a week now :(((

It seriously sucks.

huh? ive been on psn the whole time, never had any trouble, what region are you guys in?

I've had some trouble logging in but usually it doesn't take many tries to get in. Well, usually it's the second try that succeeds. Oh, and I live in Finland, just in case it matters (and it should).

It wont auto sign in for me anymore when i turn my ps3 on, but i give it a second and sign in again and bam! back in business, my first though was anon but could just be Sony, maybe they're updating steam to work better with/PSN

I'm from the UK

Mine doesn't auto sign in at the moment either, but if I turn off the media server, it does :)

Same issue, so I will try and turn off the media server

Ive been able to sign in but havent been able to play any black ops multi or crysis 2 multi, for some reason everytime Id try joining a match it would stay stuck on the searching for a match screen.... annoying to say the least.

I have initial sign in issues.  Everytime I turn my PS3 on, it fails to sign in that first time.  I try once more and it works, and stays logged on from that point.

Been happening for about a week.

I did post a work around that actually works. But whatever . . .

Do you have media server turned on?  I've always had issues where it never auto signs on if this feature is turned on, I have no clue why.
