My previous employer has this happen with OCI (Oracle's cloud). Hundreds of servers suddenly deleted do to a internal billing problem on Oracles side. Luckily they were able to restore from backups, but it took a full day and there was still significant data loss (the delta since last backup). Since those servers were used to host the companies own cloud managed offering it ended up affecting all of their own cloud customers as well.
