Wow, what a disaster! Well done Ugobe for taking their site down in the most busy holiday buying period, if you really wanted to mess things up then you certainly went about it the right way.
For those who are not in the know: Ugobe decided to move their website from a datacentre server (no idea if it was shared or dedicated) to their own server in-house, however obviously they didn't time things right and the site was replaced with a "This site has been cancelled" message for 20+ hours before changing back to the UGOBE site or a message saying "It Works!".
My personal idea for what happened behind this is that they changed their DNS way too late and cancelled their hosting before nameservers worldwide had picked up on the change, so instead of seeing Ugobe's new server, we saw the hosting site's "This site has been cancelled".
We have also had no forums for over 24 hours, not the way to help a growing community pleoworld!
