So it turns out that the cause was indeed a rogue change they couldn’t roll back as we had been speculating.

If this is how they do their routine updates, they have had an extremely lucky run so far. Inadequate understanding of what the update would/could do, inadequate testing prior to deployment, no rollback capability, no disaster recovery plan.
