With 3 programmers, I seriously doubt there is a backup for every function.

Then they either need to tolerate less than 100% availability for those functions or hire more people.

For a company of the size we are talking about, it would definitely by the former. Even at 20 people, it's not possible (financially) to have backups for every function and we have to tolerate downtime for people.
