Our other data center is the Navisite Data Center in Andover MA.

Our data centers are engineered to the standards required to support the Zero-Downtime Network. They are designed and maintained without compromise for security or redundancy. Ever.

Physical Security

• Keycard protocols, biometric scanning protocols and round-the-clock interior and exterior surveillance monitor access to every one of our data centers.
• Only authorized data center personnel are granted access credentials to our data centers. No one else can enter the production area of the datacenter without prior clearance and an appropriate escort.
• Every data center employee undergoes multiple and thorough background security checks before they're hired.

• Every data center's HVAC (Heating Ventilation Air Conditioning) system is N+1 redundant. This ensures that a duplicate system immediately comes online should there be an HVAC system failure.
• Every 90 seconds, all the air in our data centers are circulated and filtered to remove dust and contaminants.
• Our advanced fire suppression systems are designed to stop fires from spreading in the unlikely event one should occur.

• Should a total utility power outage ever occur, all of our data centers' power systems are designed to run uninterrupted, with every server receiving conditioned UPS (Uninterruptible Power Supply) power.
• Our UPS power subsystem is N+1 redundant, with instantaneous failover if the primary UPS fails.
• If an extended utility power outage occurs, our routinely tested, on-site diesel generators can run indefinitely.

• Only fully redundant, enterprise-class routing equipment is used in Rackspace data centers.
• Fiber carriers enter our data centers at disparate points to guard against service failure.

• We require that the networking and security teams working in our data centers be certified. We also require that they be thoroughly experienced in managing and monitoring enterprise level networks.
• Our Certified Network Technicians are trained to the highest industry standards.
