Computers fail in courts across England as judges and CPS try to access info

>“We will be restoring the email history of those affected over the next few days.”

Most "computer problems" don't result in the zeroing-out of mailboxes; unless the disk went down but, even then, you'd imagine that - if they did things the correct way - they'd have redundancy. Maybe they're leveraging a NAS and the NAS went down (in a relatively new system)? ...but, again, redundancy?

It definitely seems odd...
