Rock-solid reliability

Keeping your data confidential isn’t enough. We also put a lot of effort into ensuring your email and calendar are always available, and never lost, damaged, or corrupted.

Fastmail has some of the best uptime in the business, plus a comprehensive multi data center backup system. It starts with real-time replication to geographically dispersed data centers, with additional daily backups and checksummed copies of everything. Redundant mirrors allow us to failover a server or even entire rack in the case of hardware failure, keeping your mail running. Sophisticated DDOS protection means our network can stay up even when under substantial attack.

At Fastmail, we care about these things — and much more — so you don’t have to.

As part of our extensive 24-hour monitoring we test every port, on every service, along with key parts of our hardware and software. We also continually test the web interface on every backend server, with engineers on call to respond to any issues.

Transparency is very important to us, which is why you can always view our current status and track record at fastmailstatus.com.
