anacron hasn't changed in ages, and the last cron upload was 2 months
ago, so at the moment, I have no idea what could have gone wrong.
What do the log files say? Did other (non-anacron) jobs run
successfully)? Are there any failure messages for anacron?

This is by design. anacron is not a daemon, it is supposed to be started
by cron.

You are overlooking the script anacron installs to /etc/cron.d. It is
run on a daily basis, which means that all the jobs that cron is
skipping in /etc/cron.{daily,weekly,monthly} are executed by anacron.
