I didn’t catch this reference, so adding the below for other folks in the same boat:

https://en.wikipedia.org/wiki/Eternal_September

“Eternal September or the September that never ended was a cultural phenomenon during a period beginning around late 1993 and early 1994, when Internet service providers began offering Usenet access to many new users. Before this, the only sudden changes in the volume of new users of Usenet occurred each September, when cohorts of university students would gain access to it for the first time, in sync with the academic calendar.”
