Our Network Backbone Providers:

The AboveNet backbone, a Tier 1, high-performance, global optical IP network, has been optimized for scalability, survivability, performance, efficiency, and manageability. The current AboveNet network consists of a set of sites interconnected in a partial mesh extended to accommodate a larger number of sites, moving toward a 2-level hierarchy. This 2-level approach allows arbitrary scaling at either level according to various technological and business imperatives.

Level 3 operates the first global 10 GBPS (OC-192) seamless, redundant IP backbone. Level 3 has successfully constructed an international fiber optic communications network connecting Europe and the United Sates. A continuously upgradable network with high-capacity, scalable, peering interconnections ensures uncongested connectivity between the largest Internet backbone networks in the world. The average latency is 40 milliseconds or less in all regions, with less than 1% packet loss.

The MCI UUNet network spans more than 4,500 Points of Presence (PoPs) throughout North America, Europe, and the Pacific Rim and is arguably the top Internet backbone in the world. The MCI IP network maintains high levels of reliability with redundant and diverse paths to avoid single points of failure and provide optimal routing and traffic flow. The MCI state-of-the-art network operations centers provide proactive network monitoring and fault resolution 24 hours per day, 7 days per week.

The NTT/VERIO Network spans North America, Europe, and the Pacific Rim and is arguably the top Internet backbone in Asia.

Our network is now peering with more than 37 other networks at the Switch and Data PAIX (Peering and Internet Exchange) in Palo Alto. PAIX is the largest commercial, neutral Internet exchange point in the world, where major telecom carriers, Internet providers, and content networks exchange Internet traffic.

WilTel (formerly Williams) is one of the few national Tier 1 IP backbone providers in the U.S. With the nation’s largest, fully-lit, next-generation fiber-optic broadband network, WilTel delivers voice, data, video and IP services for some of the world’s largest telecommunications carriers, Internet service providers, global media and entertainment companies. Their MPLS-enabled IP packet over SONET (PoS) backbone offers superior redundancy, lower costs and unsurpassed IP reliability. The WilTel OC-48 PoS backbone has nearly 300 interconnection points nationwide.

ZZ Servers San Francisco data center was built by WorldCom in 2000. The building also houses "super-nodes" for MCI and AT&T local phone service in San Francisco, so it is considered an "essential" facility because 911 calls are routed here. We share generators, power, cooling, and fire suppression infrastructure with MCI (formerly Worldcom), including dual 2 Megawatt generators that support the critical power requirements and operations of the building.

  • Built by Worldcom in 2000 as expansion space
  • 20,000 square feet of capacity
  • Plenty of available power and cooling

Network Operations Center

The Network Operations Center (NOC) is built right in the center of our data center floor, and is staffed 24/7/365 by certified systems administrators and network engineers. The 21 screens that make up the NOC monitor everything from network traffic and performance to power, temperature and security systems to services, applications, known vulnerabilities and RAID array status on customer servers.

  • Large on-site NOC with 24/7 Engineers
  • Real-time monitoring and alerts for all critical systems
  • Customer level service and application monitoring

Building Construction

Our data center is located in the San Francisco Telecom Center, conveniently located just south of San Francisco's Financial District. This 100% occupied telecom building also houses AT&T and MCI super nodes. The building was originally built in 1924 as a Marine Corps Depot for heavy equipment, so the five story structure is built of extra-thick, reinforced cast-in-place concrete. The building was seismically retrofitted in 1999 to convert the existing warehouse into a Telecom Center in accordance with San Francisco's Uniform Building Code, and then retrofitted a second time to exceed those standards by tenants AT&T and MCI in accordance with their stringent telecom carrier standards.

  • Secure building originally used for storage of military tanks and equipment
  • Built on an outcropping of solid bedrock that also supports a tower of the Bay Bridge
  • Seismically retrofit in 1999 to meet rigorous City of San Francisco building codes, then retrofit extensively by MCI again
  • Six separate fiber entrances with 2 fiber rooms. A large portion of the Bay Bridge Fiber Consortium terminates in the building (cross-bay Fiber)
  • State-of-the-art redundant systems for power, HVAC, fiber connectivity, seismic precautions and fire suppression

Fire Suppression

Our state-of-the-art fire suppression has three levels of protection. Halon fire extinguishers are located throughout the data center. We also have a two stage TotalPac double interlocked dry-pipe preaction system, with tightly defined zones to isolate and extinguish any fires without affecting surrounding areas. This system must detect both smoke and heat to be triggered. The data center is protected by a grid of 200 sensors on the ceiling and 200 under the raised floor plus "VESDA" AnaLaser-brand laser smoke sensors that are 10,000 times more sensitive than conventional smoke detectors and capable of detecting incipient smoldering. The system is monitored 24 x 7 on-site and off-site.

  • Halon Fire Extinguishers
  • VESDA laser smoke detection with dry pipe suppression
  • Tightly defined preaction zones for localized fire extinguishing
  • Monitored and maintained by both data center staff and MCI


The San Francisco Telecom Center where our data center is located maintains the highest possible standards for physical security. This facility is home to only three tenants, MCI, AT&T and ColoServe, and is equipped with state-of-the-art video and audio monitoring equipment and 24 x 7 on-site guards. All people entering the building are required to register with the security office and leave a valid ID while in the building. Those not on the access list are not allowed into the building without an escort. We check in visitors a second time prior to entry into our data center on the second floor. The NOC is staffed 24 x 365 and is afforded a direct line-of-site view into the data center.

  • 24 x 7 security guards at front entrance
  • Secondary check-in at our second floor data center
  • 24 x 7 systems administrators / NOC on the data center floor


The San Francisco data center has tremendous cooling infrastructure, with dual redundant chilled water supply loops and multiple Liebert air conditioning units pumping cold air into the pressurized raised floor of our data center. Chilled water is provided by the roof cooling towers, which also provide chilled water for MCI's critical systems. Additional chilled water supply and return valves are already plumbed every thirty feet along the perimeter of our data center, allowing for rapid installation of additional Liebert units should increased cooling capacity be required.

  • n+1 Liebert VACs w/n+1 supply loops and chillers
  • Up to 300 tons of cooling capacity that runs on MCI's chilled water systems
  • Raised floor system for efficient distribution of cooling

Power Infrastructure

Our data center power is fed by conditioned UPS (uninterruptible power supply) electricity, with redundant feeds from dual 2 Megawatt generators that also support critical MCI phone switches. One generator can power the entire building for several days time, and there is 20,000 gallons of reserve diesel fuel on site. These generators are tested monthly per stringent MCI protocols, and every third month the power is disconnected from the two utility feeds to ensure proper generator operation.

  • Redundant power feeds with UPS power
  • 2 x 2 megawatt generators that also power MCI's local phone switches
  • 20,000 gallons of diesel fuel on site, hot-refill ready
