Looks like Analytics (formerly Urchin) is down again.

Google: I signed up for Urchin, and I expected to pay for, so I would have quality, reliable service.
Now its free, but seems to go down whenever it feels like it — and since no one is paying anymore, there seems to be no urgency on your part to communicate with your customers.
I am seriously thinking to moving back to a paid platform. Any suggestions out there?
