Let me call Google and ask them to reboot Analytics. It might take a while to crunch through the stats log so hold off applause for a day or two.
Yea, it's getting worse slowly for me. It started tracking for me again yesterday, but both versions showing different numbers. Now today it's not tracking anything for any of my sites for either version. Hurry up and fix it Google gods!
It might be a problem in certain locations (side note: show your general location in your personal info!) if those that are reporting things are all right are correct. The US, Canada, and Pakistan appear to have problems while some Euros don't.
I was looking at yesterday's stats today in the old version of Analytics and noticed that traffic dropped significantly for most sites I track. Also, conversion tracking was off because I know for a fact one website had 13 conversions, for example, and Analytics says 9.
