Service Alert: Mail SSD Backend Announcement

We’re pleased to announce that following months of behind-the-scenes work, all Mailcore and wholesale email mailboxes are now stored on SSD, using the most advanced filesystem in the world, ZFS. This gives us numerous advantages, including faster performance, improved reliability and less energy consumption. ZFS gives us instant snapshots and guarantees against filesystem corruption as well as adding even more performance due to its advanced memory caching scheme.
