I just received a call from a financial trading company based in Singapore. Their business requires the lowest latency since a delay in executing a 100-million dollar trade can cost millions! They have been paying for two carriers, each providing DS-3 connectivity to their sister facility in Tokyo. They were accustomed to 80ms latency. When the APCN cable was cut on August 11, they discovered that their redundant DS-3 ran on the same APCN cable. Performance degraded severely enough to hurt their business.
The lesson: using an MPLS Expert can assure that the network you have suits your requirements for performance and security. Rarely does the discussion of specific cable infrastructure arise in the procurement process. But your network performance depends on it!
