When Hurricane Sandy ravaged New York, Internet and phone connections were disrupted across the city, but OnSIP experienced no downtime. What makes OnSIP’s hosted PBX platform so reliable? How do our redundant servers, routers, Tier 1 Internet connections, colocation centers, and upstream carriers interact to offer a platform that is uniquely superior and seamlessly scalable?
For starters, OnSIP is not comprised of customer PBXs deployed in a datacenter. OnSIP consists of a geographically distributed cloud of SIP proxies that present themselves as a single SIP server (sip.onsip.com). OnSIP phones connect to the geographically closest SIP proxy in the cloud. This unique infrastructure allows for optimal call routing, no service outages if a single box fails, and massive scalability. In the case of Hurricane Sandy, we routed customers from our NY data center to our LA data center in preparation for the storm. As result, OnSIP was not affected by the storm. In 2012, OnSIP had 99.9% uptime.
