The Data Center:
The primary data center is located in a secure, underground Los Angeles
facility which was originally designed to be the hub of a National Banking ATM network.
At a cost in excess of $300 million, the facility was engineered for extremely high levels
of security and reliability.
Data Center Features:
The Data Center is backed by four 750KW UPS modules with 480 batteries
to provide continuous uptime in the event of a transition to emergency generator power.
Four 1100 kilowatt and one 1250 kilowatt diesel generators are connected in tandem,
with enough fuel to power the facility at full load for a month without the need for refueling.
HVAC units consist of three 1000-ton and two 500-ton centrifugal chillers with four
1500-ton cooling tower cells, roughly quadruple the capacity necessary to cool the entire facility;
all units are tied into the emergency generator and UPS system, which
allows for cooling to
continue in the event of an extended power outage.
24x7 on-site manned security guards. Biometric key card's and video
surveillance systems cover all areas and entrances within the data center.
Multiple Gigabit Ethernet connectivity to first-tier Internet backbone providers
including AT&T, Level3, MCI, Savvis, Sprint, Verio, and Verizon provides redundancy
& failover.
The software in use is scalable and proven. Systems are built upon a hardened version of
Red Hat Enterprise Linux, optimized for the particular demands of high-volume SMTP processing,
a combination of other open source software, along with other proprietary software components.
Network Redundancy:
The primary data center is augmented by an autonomous,
redundant second facility on the east coast. This distributed architecture provides a
highly reliable and scalable network service platform.
