This couldn’t be anything to do with systemd + keepalived, could it? Somebody on Andrews & Arnold IRC has just written
——————
GAH - Systemd + Keepalived is "dangerous"
I've just experienced systemd removing IP addresses underneath keepalived
which older versions of keepalive have no idea on!
This leads to Keepalived saying "I'm master and all is OK" when checking "ip addr" says a very different story :/
This only seems to be an issue on Ubuntu though
machines with Debian seem to not have this problem

Apologies if I’m way off the mark (and for the formatting)!
