| 100% Uptime |
Businesses rely heavily on email for central business processes like customer transactions, vendor relationships, and internal communications. Our industry-leading 100% uptime guarantee is a reflection of both our understanding of email's central importance to many businesses and a reflection of the high availability email system engineered by our experts.
The Email hosting approach is to high availability popularised by Google: large numbers of computer servers built on commodity hardware. The basic theory is that server failures are common, so arrange servers in pairs or clusters, then build failure detection into the network or the software.
Key services are spread across large numbers of servers in single-purpose clusters. Our experience has shown this greatly reduces the risk that any service might become unavailable to our customers.
