"Hello,

it turns out we probably caused the downtime ourselves. I didn't know dropping 170 databases and deleting 80 entire projects at once could do that"

Gave me a hearty chuckle. Especially as the client adamantly refused to have SSDs installed for the DB to run on top.

Just imagining the poor read-write heads jerking back and forth in vain attempts to find all the data to delete... So yes, dropping 170 databases at once does in fact take a database server down to its knees, as deleting is all the drives will be doing for a while.

At least it wasn't my or my colleague's mistake this time.
