We
understand the importance of speed, security, and
stability, and have invested heavily in hardware and
facilities that ensure your sites are up and running
on the web 24 hours a day, seven days a week. We have
conducted many hours of research looking at all of the
top network providers and have given special attention
not only at their current network topology, but also
their financial outlook and past financial
performance. With the telecommunications market
fluctuating constantly, we so must be evaluating the
top telecommunication companies that play a pivotal
role in the design and operation of the internet.
AT&T
provides us with a Tier 1 Internet backbone for all of
our internet servers. AT&T offers a diversely high
speed network with optimal peering points into
secondary networks around the world. Of all the
Internet hosting providers around the world, AT&T's
networks, customer support and facility infrastructure
places AT&T as the leader for internet connectivity.
Some hosting companies would probably disagree with
the above statement, putting costs in front of
service. There are hosting companies which are cheaper
than AT&T. However none have the redundancy and
network infrastructure comparable to AT&T. It is for
this reason that we have chosen AT&T as our network
service provider. They are clearly the best!
AT&T Internet Data Centers
AT&T has a network of world-class
quality web hosting centers around the world. AT&T
Internet Data Centers (IDCs) are optimized to provide
an industry-leading web, data, and applications
hosting environment. These centers are
designed
to stay up and running, protected from power failure,
physical intrusion and network outages by extensive
back-up power and cooling systems, multi-layered
security, and network redundancy and diversity.
AT&T IDC network includes 18 centers
operating on three continents and in 11 different
major U.S. markets. All of these locations were
carefully selected to be on or near a central network
peering point to ensure the greatest geographic
diversity and to maximize reach and performance.
AT&T is setting the stage for the
next generation of Web hosting and business Internet
solutions. Here’s why:
Network
AT&T IDCs have network access capacity of 7.2 Gigabits
on an AT&T Local Services ring that is redundant and
diverse. Dual access routers connect IDC to multiple
AT&T IP backbone nodes via dual OC-48 connections.
Back-end connectivity and network services options
available include ATM, Frame Relay, private line,
IP
and local-switched, and circuit-switched services with
local access provided by both AT&T and the incumbent
local service provider.
Security
Security is provided 24X7 and includes guards,
closed-circuit monitors, alarmed doors with secure
card-key access, biometric scanner, “man-trap”
restricted access to the data floor and options for
locking equipment enclosures (cabinets or cages).
Guards maintain access to the loading dock and access
requires a card key. Security personnel also monitor
the building. Building and environmental alarms are
monitored locally by a 24X7 maintenance staff and also
remotely by the AT&T Network Operations Center.
Power
AT&T IDCs are designed for 90W/sq ft of raised floor.
Most have dual (2N) Uninterrupted Power Supply (UPS),
each with multiple modules synchronized to work in
unison or independently. UPS systems receive power
from both commercial power feeders and standby
generators and are designed to support a fully loaded
center for 15 minutes via its internal battery plant.
In case of a commercial power
failure, banks of diesel generators in an N+1 design
(at full load) provide power to the center within one
minute of a commercial power outage. The one-minute
gap is covered by the UPS battery system to ensure no
impact on equipment. During an extended commercial
power outage, the diesel generators provide power
using the fuel stored in underground tanks. The diesel
generators provide power using fuel stored on site.
Fuel suppliers are on standby to provide additional
service.
Fire Suppression & Detection
Smoke detection is via a state-of-the-art VESDA (air
sampling) smoke detection and alarm system. Fire
suppression is via a pre-action dry pipe system. VESDA
systems are 100 times more sensitive than conventional
fire detection systems. Detectors are grouped into
zones. When one or more detectors 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 head will melt and
discharge water on the affected area.
Risk Assessment
AT&T IDCs undergo an extensive set of AT&T
standards-based risk assessments to ensure that they
are at low risk of outages, as well as flood,
earthquakes, wind, and other physical risks. Several
sites have (San Diego) or are undergoing (Chicago area
& Secaucus) SAS-70 certification (type 2 test - most
strenuous). All AT&T IDCs adhere to these same
standards of reliability and resiliency.
