Email is the most important business communication tool, and Rediffmail knows that when email is down, business is down. Our industry-leading 99.99% uptime guarantee is a reflection of both our understanding of email's central importance to businesses and the high availability email system engineered by our experts.
We tried the more traditional design approach: high-end servers with high-end disk subsystems. The mean time between failure (MTBF) was only somewhat better than commodity hardware, although the high-end server hardware was many times more expensive.
Rediffmail developed a unique system: large numbers of computer servers built on commodity hardware. Server failures are common, so we arrange servers in pairs or clusters, then build failure detection into the network or the software. This built-in redundancy greatly reduces the risk that any service might become unavailable to our customers.
