Reliability Our lines are protected against any physical disruptions, and we have never experienced a switching-module failure. To protect against power failures, all our locations have (and regularly test) both DC and AC backup power systems. And we’ll work with you to produce a detailed Disaster Recovery and Business Continuity Plan specific to your needs and architecture. The plan includes contact points between companies, full written procedures for recovery, decision points for business continuity and a variety of other issues.
