While it's obvious that the Y2K bug didn't have the apocalyptic impact that people were freaking out about, I was curious if anything major broke/malfunctioned/did-something-unexpected because of it.
I'm currently consulting on a workforce management SaaS. (Think of workforce management as a time clock where people can punch in and out).
It was interesting to learn that starting in 2015 some customers were having trouble generating payroll for their youngest employees (aged 16 years) at the time. In debugging the issue it was concluded that Y2k was the issue (sort of).
I was a contractor at a Fortune 500 company in 1999. We had a six month code freeze. We couldn't even make changes to development. So I was very bored. Taught myself PalmOS development while I waited.
Peachtree changed their tune early on from "Yes it will work past 2000" to "We only support versions beyond version Y for the Y2k changeover" (no direct mention that the older versions will work)
Many publishers' tech support got ran over by marketing to con people to buy new software/hardware based on various real and imagined FUD. Y2K was a big inspiration.
I remember hearing of isolated incidents, but nothing major happened that I'm aware of. I guess the biggest thing to happen was a lot of COBOL programmers made pretty good coin leading up to January 1, 2000.
