This is not remotely rare in web hosting. If you're on a shared host and over consume resources you'll be shutdown before the admin has a chance to even generate a ticket. Some hosts don't even generate a ticket, they just suspend the account with a page that informs the owner that they've over consumed resources.
Not saying it's great, but when you're dealing with hundreds of thousands of VPS/cPanel accounts and one account affecting 5000 other accounts on a server you're sometimes forced into a corner where you have to act as quickly as possible.
