I doubt that you're posting in the wrong section... But anyway, YouTube is not down, Not even for 3 minutes. lxguy's comment seems to be right then; LOL pwnt.
Youtube is usually almost always uptime and some temporary issues could be related to your ISP connections.
Their videos are loading really slowly for me. And, sometimes they don't even want to load at all. I know it's not my internet connection because I've been using other websites just fine and my connection is perfect. They need to put those billions of dollars in revenue to good use and buy some more servers. Yugo,
