We don’t expect our servers to operate indefinitely without failure. We know from experience that any equipment can fail. When it comes to network availability and “up-time,” we believe the best approach is to build multiple layers of redundancy into a vendor-agnostic, commodity-based architecture. We also believe that our architecture IS our technology—which is why we treat this knowledge as strategic, closely guarded information. We don’t reveal the details of our configuration to anyone. We utilize many load balancing and failover technologies to keep our telephony systems continuously up and running. For example, we designate primary and standby servers in each of our data center locations to maximize redundancy.
