They recently shut down all the servers of a Chinese reseller with 45 servers after a lot of their servers were the target of a DDOS. It's of course understandable to disable those servers in case of a big DDOS, but the problem was that they gave the reseller 24 hours (during the weekend) to backup the data.
It's pretty much impossible to do this in the weekend without even the passwords of the customers. Imagine receiving this email when you wake up (probably some time after it was sent) and having to get new servers immediately somewhere, emailing/phoning customers for their passwords and then also having to transfer potential TB's per server in the small remaining time frame. After posting on WHT (meaning after a PR disaster), 100TB did extend the deadline.

I was considering them for a high-bandwidth project, but after reading these cases I changed my mind.
