Though a friend at another related service had been kicked from two VPS providers due to receiving a few DDoS attacks.
These providers claimed it was against their Terms of Service and ejected him as a customer.
That day he learned it is best to keep offsite-cross-company backups of everything, since he did not get a single byte from his machines.
Who are these providers that just delete client data? I run a small datacenter for our niche of clients and when the contract terminates or the project is finished I box up all their data and fire it off to S3.
Storage is so cheap these days there is no excuse not to keep client data for at least a month.
Claiming it was against the terms might be an easy out for them but is silly since being a target is outside of your control, for the most part. Hosts will usually null route customers without sympathy to protect other customers so it's the price of doing business.
