Our Network

DNS and Gateway Services are operated by Point Clark Network's Distributed Network -- a combination of servers and clusters in different geographic locations.  The infrastructure was designed to be:

  • Secure
  • Reliable
  • Scalable
  • Fast

Distributed Network - Status

The table below lists the status of all the systems in our infrastructure.  The infrastructure is designed to be robust.  In other words, if several of the systems are offline or busy, the other systems in the network will take over the extra workload.
