"I’m not convinced that they did everything they could to prevent the seizure of non-targeted servers, and their lack of proactive communication with the affected customers is beneath the level of service I expect from a host." I can't speak to the level of service you did or did not receive but I seriously doubt DigitalOne could have done more to prevent "non-targeted" servers from being seized. If it was in the same rack as the "targeted" server I'm sure that 100% of the time LE would take it and find out whether it was related later. It's their job to take every step necessary to preserve evidence first and foremost when executing a search warrant like this. I agree with you that the data was almost certainly not compromised and I think it's great that you're so proactive about protecting your customers by moving to bcrypt.
