Having never really gone to the cloud, thankfully, FastMail can strongly recommend New York Internet if you're looking for a datacentre provider. They've been amazing. https://blog.fastmail.com/2014/12/10/security-availability/ https://blog.fastmail.com/2014/12/10/security-availability/ Actually, we don't appear to blog quite enough about how awesome NYI are. They're a major part of our good uptime. And some stuff about our hardware. I'd strongly recommend hot stuff on RAID1 SSDs and colder stuff on hard disks. The performance difference between rust and SSD is just massive. We're looking at PCI SSDs for our next hardware upgrades: http://www.intel.com.au/content/www/au/en/solid-state-drives/intel-ssd-dc-family-for-pcie.html http://www.intel.com.au/content/www/au/en/solid-state-drives... (there are two types of SSD on the market. Ones that lose your data, and SSDs from Intel) - we're currently running mostly DC3700 SATA/SAS SSDs. We customise the layout of our machines very much to match the heat patterns of our data: https://blog.fastmail.com/2015/12/06/getting-the-most-out-of-hardware/ https://blog.fastmail.com/2015/12/06/getting-the-most-out-of... https://blog.fastmail.com/2014/12/15/dec-15-putting-the-fast-in-fastmail-loading-your-mailbox-quickly/ https://blog.fastmail.com/2014/12/15/dec-15-putting-the-fast... https://blog.fastmail.com/2014/12/04/standalone-mail-servers/ https://blog.fastmail.com/2014/12/04/standalone-mail-servers...
