servers are housed in a modern data center in Parsippany,
New Jersey. The network has been engineered from the ground up
to accommodate the high-availability demands of the Internet's
most popular websites. The data center and network have been
optimized to provide the highest level of reliability.
data center utilizes connections to multiple backbones to ensure
that data reaches the end-user in the fastest, most efficient
manner possible. Network providers include AT&T, Broadwing,
Qwest, SAVVIS, SBC, Time Warner and UUNET. There are also peering
agreements with local ISPs to allow fast delivery of packets when
The data center is physically isolated from everyone but
level three technicians. Public access is strictly forbidden.
Access to the floor the data center resides on is restricted
to those holding military-grade passcards. Furthermore,
access to the data center itself is restricted by Biometric
Power systems in the data center are designed to run uninterrupted
even in the unlikely event of a total power outage. All
servers are fed with conditioned UPS (Uninterruptable Power
Supply) power that will run if utility power fails. The
UPS power subsystem is N+1 redundant with instantaneous
fail-over in case the primary UPS fails. In the event of
an extended power outage, an on-site diesel generator can
run indefinitely. The generator is regularly tested to ensure
that it will continue to function in the event of an emergency.
The data center is meticulously tidy. All air is circulated
and filtered every 90 seconds to remove dust and contaminants.
The data center's HVAC (Heating Ventilation Air Conditioning)
system is N+1 redundant to ensure that - even in the event
of an entire HVAC system failure - there is a duplicate system
on standby to take over. An advanced fire-suppression system
is in place to prevent any fire from spreading - in the unlikely
event that one could start. All cables to servers and routing
equipment are securely tied down, and cable racks suspended
from the ceiling provide dual routes for all cables. In the
event that all cables on a cable rack are cut or burned, packets
of data will automatically be routed to a second set of cables
on the other side of the data center.
