Architectural Section Building Raised Floor Specifications: Loading and Receiving Dock: Power Watts / Square Foot: Raised floor for equipment spans the entire computer room area. Allowable load for the tiles is 150lbs per square foot. Loading dock facilities are available. Onsite security personnel monitor access to the loading dock. Customer shipments to the IDC require customer site ID # on all shipping labels. No unidentified packages will be accepted. The Power Density meets AT&T Internet Data Center Standards and IDC Industry Tier 4 Standards. Commercial Power: Standby Generator Systems: The Internet Data Center has one (1) commercial power service feed for this building. Seven (7) - 2,000kW diesel generators providing standby power to the Internet Data Center. N+1 redundancy exists throughout all phases. There are two 20,000-gallon underground diesel fuel storage tanks at the site. Uninterrupted Power Supply: Grounding Architecture: Commercial Power Contingency Arrangements: Environmental Controls HVAC Distribution: HVAC System: HVAC Redundancy Architecture: HVAC Contingency Arrangements: Fire Suppression: Four (4) - UPS systems, each with two (2) - 675kW/750kVA modules. Three systems act as primary source of power and the fourth system works as standby system. Each UPS system can support its designed full load of 1350kW 1500kVA (each) for 15 minutes via its internal battery plant. And Two (2) 3,000 kva/2,400 kw UPS in 2N configuration, with 15 minute battery life. Perimeter ground ring is tied into driven ground rods. The UPS systems, equipment cabinets, racks and associated metal parts are tied into the ground ring. In case of a commercial power failure, the standby generators provide power to the Internet Data Center within one minute of a power outage. The one-minute gap is covered by the UPS system. During an extended commercial power outage, the diesel generators can provide power for 96 hours using the fuel stored at the site. There are processes and procedures to connect a portable generator to ensure N+1 redundancy. The building has five (5) - 750-ton chillers, (with provisions for the addition of another - 750-ton chiller to accommodate future growth). Air Handling Units are redundant. They provide humidity control and air filtration for the computer room area. The raised floor, which is used as an air plenum, delivers conditioned air to the equipment cabinets/racks via the CRAC units. There are ninety eight (98) 20 ton CRAC units are strategically located on the raised floor area. Designed to AT&T Internet Data Center Standards and Industry Tier 4 Standards. Currently there are three (3) - 750 ton chillers to carry the site load with two (2) 750 tons chillers in standby. This represents an N+2 configuration. If a chiller fails, a standby chiller can carry the load continuously. Operations can choose to operate all (or some of the) CRAC units that share the cooling needs evenly operating at less than full capacity. If a CRAC unit fails, heat load gets distributed automatically. The Internet Data Center has pre-action dry pipe fire suppression system supported by a state-ofthe-art VESDA smoke detection and alarm system. The VESDA system is considered 100 times more sensitive than conventional, passive fire detection systems. Conventional smoke detectors are also utilized and are grouped into zones. When one or more detectors in different zones detect smoke, the fire alarm panel opens the deluge valve to fill the sprinkler piping with water. In case of an actual fire, the seal on the sprinkler heads will melt and discharge water on the affected area. Water will not be discharged in unaffected areas.

Risk Assessment General Information Site Description: The site is located in a region of Low Seismic Activity. The building meets current seismic code. There are no major faults in the area. Building Description: The Web Hosting Facility is located in a three story building which originally functioned as a corporate data center, which has been totally re-purposed for hosting use, (no corporate data functions remain). The building was constructed in 1985. The building has structural steel moment resisting space frame construction with cast-in-place concrete floor slabs. The building has pre-cast concrete exterior wall panels Floors designed for the following live loads: Elect. (Battery rooms @ grade) = 300 psf, Web Hosting floors = 150 psf General Condition: Building appears to be in good condition. No significant signs of distress have been observed. Earthquakes Hazard Assessment Seismic Load Site Class D Ground Shaking Hazard: Low Soil Liquefaction Hazard: Very Low Soil Compaction Hazard: Very Low Fault Rupture Hazard: none Tsunami Hazard: none Landslide Hazard: none Mesa 4 of 6
Risk Assessment - continued Building Risk Assessment: Web Hosting Building There is a very low potential steel frame connection damage, due to the very low seismic zone. No life safety hazards identified Equipment Risk Assessment: Equipment Anchorage Description Risk Assessment Data Center Racks Anchored to raised floor tile and tiles locked to raised floor framing w/ unistrut. Low Overhead Auxiliary Framing Suspended racking braced per AT&T Standards Low Raised Access Flooring Web Host Area Only Low CRAC Units Anchored to the concrete floor slab via steel stands through the raised floor. Low PDUs Anchored to the concrete floor slab via steel stands through the raised floor. Low UPS Anchored to concrete floor slab on concrete housekeeping pads. Low Switchgear Anchored to concrete floor slab on concrete housekeeping pads. Low Electrical conduits Supported per AT&T Standards Partially run underground Low Chillers Sit on spring isolators which are anchored to floor slabs in Mech. room Low Chilled Water Piping Supported per ANSI B31.9 Low Generators Anchored to concrete foundation on concrete housekeeping pads. Low Cooling Towers Supported by elevated steel structure and anchored to concrete foundation Low Regional Disaster Effects on Site Loss of Power: Power supplied by 1 utility feed. Standby generators can maintain power supply 48 hour diesel fuel storage on site Loss of Water: multiple utility feeds and multiple independent tanker supply providers. Network Connectivity: Two diversely routed telecom duct banks provided. Summary: Site is in general well prepared to resist the effects of an unlikely earthquake. Windstorms Hazard Assessment: Factory Mutual Design Wind Speed: 90 mph (3 second gust) Factory Mutual Ground Roughness Exposure Category: B Overall, lateral wind loads during a windstorm are more severe than earthquake loads at this site. Historic windstorm risk is very low for this location. Mesa 5 of 6
