It's been one of those weekends: Best Internet, our ISP, has erased the DNS entry for the Internet Nexus in error and will try to get it back up "as quickly as possible," which is Best-ese for "when it's up." In any event, you can reach the site now by trying it's IP address but these problems have caused me to delay the release of the new site until later this week (or whenever the site is up) because most of the internal links are code to the domain name, not a relative path. I did this so I could test it at home and not need to download all of the graphics, which seemed like a really good idea at the time.
Sadly, Joe and I pulled an all-nighter last night to finish the Nexus personalization code, which is actually pretty amazing stuff. We're looking forward to sharing it with everyone, but we decided to give this DNS problem a few days to iron out. Sorry for any inconvenience this causes,
