I was involved in several of the efforts at the time including building the communications systems for the "studio NOC" at AT&T in NYC. I started hearing about vulnerable systems about 5 years before 2000 and we were doing serious work on those systems about 2 years before. I predicted (to friends and family who didn't always care to believe me) that it would be a non-event because disruptions would be localized in smaller systems (we were expecting local banks and credit unions). Even I was blown away by how few of those systems had problems. So know when people say Y2K was no big they fail to recognize the work that went into to ensuring it was a non-event. There's a very current equivalent - if we're good about social distancing, people may talk about COVID-19 the same way.
