No..Its not just your computer..Twitter has been inaccessiblbe today due to a denial-of-service attack. And Facebook has been a little unresponsive as well... It's normal to get angry about downtime at a site you use every day, but in this case it might not be a bad thing. Why not take this opportunity to catch up on some chore you usually postpone in favor of updating your status or reading other people's tweets?( a.k.a. being NOSEY ! ) Why not try to remember what you used to do with your life before the Facebook / Twitter icons made their way onto the the home screen of your iPhone?
