Jesus christ, can all you kids calm down! so the psn is down for a few hours and a bunch of you start calling foul on Sony AND demanding free things?! they dont owe you anything...have a little patience...
i know how to fix the error, go to your connection settings, your and scan, put in wep if required and do everything automatic, but when it comes up to your DNS go to manual, for primary DNS type in 4 .2 .2 .2 and for secondary DNS type 4. 2. 2 .1
This worked for myself and hope it works for you all too share the knowlege and help people get back on line
FYI if it does not work switch the primary and secondary DNS around there have been reports of 4221 working for the primary and 4222 as the secondary.
Thanks snipe_hayk worked great for me.. You're awesome. I live in Los angeles, CA and have at&t as an ISP
