I guess you already know, but just in case you don't - opening this ticket. I did not see it showing red in nagios, neither it is in plan for this week.
It should be back now... I know what caused it and will fix that later this morning. :(
Sorry for the unintended outage.
Fixed in ansible commit d92ff41412d7c46d9e7ff2ac9635000e5419952c
