This URL is for those who have geek-like tendencies. I knew when eBay went down tonight that there'd be lots of posts here. Didn't know what the internet traffic report might show. Turns out that the rest of the US is OK, so I guess it's eBay that's fried.
For a less-geeky graph, you can try this link - it shows 24-hour traffic. 7-day and 30-day graphs are also available.
