This was the best site online for original Netrunner. I didn't play original Netrunner, but I still found it useful if I wanted to compare new cards or rules to old, or as a resource to link to for people looking for original Netrunner info.
It looks like the site owner just decided to stop renewing the domain. (Or he neglected to renew it, but I think you get a fair number of reminder emails before your registrar can replace your site with an ad.)
I've grabbed a probably-complete copy of the site from the Wayback Machine, and I'm a little tempted to put it up somewhere, but I'm not sure I want to be responsible for it into the future. Does anyone have any better ideas for what to do with it?
