High Speed Network
US Internet is connected to the Internet by one OC-3 and two DS-3 links which are carried over two different OC-12 fiber optic SONET networks. USI also maintains a copper connection to Sprint in case of catastrophic SONET failure. The USI network is connected to three peering points on the Internet, allowing for a high degree of redundancy and routing flexibility. US Internet consistently places in the top 96% of the Keynote Business 40 Index, which benchmarks website responsiveness.

Redundancy
USI data center facilities are powered by two separate Xcel Energy grids and equipped with multiple 75 KVA full time inline UPS equipment. In addition, a natural gas generator and 250 KVA Diesel generator are located onsite in the event of a sustained electrical outage. USI also contracts with a mobile power source for generator redundancy.

USI offers state-of-the-art firewall and layer 4 switching technology for maximum availability and uptime. All USI core services are complete and n+1 redundant, providing maximum fault tolerance.

Security
Physical access to the data center is controlled via a locked pass code entrance. All data center equipment is stored within secure rack mount enclosures. The data center and adjoining areas are under 24 hour video surveillance.

To prevent unauthorized network access, US Internet utilizes a combination of technical platforms to counter attack all known methods of compromising the core network. Technologies include Cisco PIX firewalls, Foundry Server Iron load balancers and F5 firewall/load balancers. Firewalls are utilized to restrict access to the network and filters have been added to the routers and the switches. IP restrictions and username/password authentication are utilized where appropriate. US Internet also utilizes a pro-active monitoring platform to proactively determine potential intrusion. These methods individually and in conjunction with each other provide the highest level of security.
