Apparently PSN uses Amazon's servers (just like Saurik does with Cydia) and their outage caused it to go down. It affected Reddit and Formspring too.
I don't know if it's Anonymous or what, but Playstation has announced on their blog that PSN will be down for a day or two. Here's a link to the post. http://blog.us.playstation.com/2011/04/21/latest-update-on-psn-outage/
"Happy Spring Break!" "Oh, sweet! I can't wait to have a snowball fight with my friends!" 2 sentences I never thought I'd see relating to each other perfectly.
Hey. On FrederickGeek8's server I was roaming around and went by your house, and a creeper sort of creeped up behind me... And I don't have the materials to build the mall portion back. Anyway I can help? :/ I'm sorry.
if you delete the launcher and the minecraft.jar currently there, then redownload it off of minecraft.net it should redownload for you. I ran into that problem too. I think I just scrapped the whole folder except for my 'saves' and 'texture packs'.
