Worked for a local IT company. I was more of the telephony/infrastructure guy than hands on servers/PC’s at the time. We just installed a brand new VOIP telephone system. Remember calling the main line at 12:01 and, leaving a voice mail making sure it was up and running and then resuming my quest for inebriation.
All in all, was pretty confident there would not be sweeping Y2K bug issues based on what I’d heard/learned at work. For sure would have been major issues if the issue wasn’t addressed. Probably not as bad as people thought, but definitely big problems.
