Longest-Serving Web Server?

frisket asks: "The Sun IPX formerly known as curia.ucc.ie (now imbolc.ucc.ie) entered TBL's CERN main menu in 1992 to serve the CURIA project (now CELT) as a search engine (running PAT). The same machine is still doing the same job, and we're trying to find out if it really is the longest continuously-serving Web server. Does anyone know if any of the other links from that page at the time (has anyone a copy even?) are which are still served by the same hardware?"
