It happens all the time, and it doesn’t even require coordination, just synchronized intent.

Examples:

- ai.com launching with a super bowl ad and being taken down just from large sign up volume

- Taylor Swift drops an album on Spotify, everyone rushes to stream it, crashes Spotify

- random small websites get featured on reddit front page and get hit offline

> how large would the number of users need to be

depends on the target. small website on shared hosting could be hit offline by 1000 concurrent users. major platform might need millions of users concurrently hitting write paths, not just loading cached/static content. or all requiring open sustained connections

> what would they have to do

just all do the same thing at the same time.
