I worked New Years 1999 when I was at Red Hat. Leading up to the change over there was a lot of work to make sure all the systems would be OK, and that underlying software would also be OK, but keep in mind, auto-update on the Internet wasn't super common. I ended up getting one call from a customer that night where they had a valid Y2K bug in their software, and since it wasn't in Red Hat's system, they moved along to their next support person to call :) It was a thing, but much less of a thing because of the work put into getting ahead of it.
