Superb's Proprietary Physical Network Infrastructure

The physical layer of our network consists of a number of interconnected private OC-192 SONET rings. Our Virginia & DC multiple OC-192 SONET rings are operated by Level 3 (formerly Looking Glass Networks) and Cox Communications. In Seattle, we rely on OnFiber, Q.West, ELI and Integra Telecom redundant SONET rings.

Our transport between Ashburn, VA, Chicago, IL, Palo Alto, CA and Seattle, WA is provided over redundant Level 3 and Global Crossing SONET rings. For transport to New York we are using Level 3 (former Looking Glass Networks). All of our fiber carriers are financially healthy and well-known major telecoms, with proven 100% uptime and reliability—Looking Glass Networks, Level 3, Cox Communications, OnFiber, Q.West, ELI, and Integra Telecom.

The OC-192 SONET rings consist of two redundant OC-192s, traversing two separate paths and having two diverse routes to our facilities, thus providing the ultimate in reliability and performance. Consider this technological miracle: Even if both of the lines are cut at any point, the SONET ring is still operational, with less than 50 ms (0.05 second) self-healing restoration time.

The multiple private SONET rings provide us with the ultimate in reliability: no downtime, ever, even in the case of a major fibre cut in the area (due to separate paths and multiple fibre carriers).
