SQL Server Data Mining is still down after a week. We had been using a free hosting service for the site ( a favor from a friend ). However, since I annouced the site last week to over 500 people at the BI Power Hour at TechEd in Orlando, the site's been down. We can't even ping the machine.
So, this week we are switching off the favor onto a reliable colocation hosting service. Hopefully we'll be back online by the end of the week, early next at the latest. We are also upgrading the server to the latest CTP, which allows us to write a bunch of new applications that we simply couldn't do on Beta 2.
Keep your fingers crossed for the rebirth of SSDM.com!
