In reference to an ATC system failure- don/t know to what extent the system would be affected in Y2K. But do know how bad air traffic would be affected using non radar techniques. Reality is, you would be lucky to see 10% of all air traffic operating. Example you were flying from Chicago to New York tommorrow and Cleveland Center loses radar coverage. If you are currently in CLE airpace ATC would revert to non radar tehnique requiring extensive miles-in-trail seperation until clear of CLE airspace. All traffic from CHI to NY would be ground stopped until a reroute was established circumnavigaing CLE airspace. This would involve a routing south of CHI then turning east somwhere between Louisville and Nashville, continuing east thru W.Va then vectors northeast for NY terminals. This example costs some time and fuel but i/ve seen it much worse. Point being, ATC is setup to operate under optimal conditions and the worst scenario of any is a radar outage. Also let me say, ATC does a fine job for the archaic tools they work with, but shut down the computers, and you shut down the airlines.
