Our servers are fast, reliable, and secure!
WebTwister recognizes that downtime
is not an option for your servers. That's why we invest heavily
in hardware and facilities that ensure that your clients are
up and running on the web 24 hours a day, seven days a week.
WebTwister's Network Operations Center
(NOC) features raised flooring. This enables a constant flow
of conditioned air and helps to maintain uniform room temperature
at all times. In addition, raised flooring reduces static
and ensures a professional, computer-grade environment for
your servers.
The facility is equipped with a Raytheon
fire suppression system, designed to immediately extinguish
fire and protect equipment and personnel. The command center
is controlled via automatic doors to further secure and protect
the equipment.
Finally, the NOC is located in a secure,
monitored, class A building with a minimum number of approved
personnel allowed access to highly sensitive areas and equipment.
A detailed record of employee and visitor entry is maintained
at all times.
To guard against local power failures,
WebTwister has two industrial-grade, three-phase Liebert UPS
systems. These act as back-up batteries, maintaining uninterrupted
power in case of surges or power outages. With these back-up
systems in place, we can keep our network up and running indefinitely
without relying on external power.
All of WebTwister's custom web servers
are equipped with a positive-pressure filtered-air system.
Four large fans pull filtered air into each server's protective
case, and the components within are cooled by fans that circulate
this purified air. This constant introduction of clean air
into the case creates a positive pressure environment ensuring
that dust and particles remain outside the server.
We keep spare servers online of all
CPU configurations. If a server were to experience a hardware
failure, we would turn a key, grab the handle on the drive,
pull it out and insert it into an identical standby CPU. We
would then reboot the second machine, and the server would
be up and running again in a matter of minutes.
Connected to Three Backbones (Network
Redundancy)
The WebTwister NOC, located in Baltimore, Maryland, is OnNet
with GlobalCenter (GC), Qwest Communications and GTE through
three separate bandwidth-on-demand connections that enter
Baltimore in our building.
GC, a Tier 1 provider with a 13,000-mile
fiber optic network and Dense Wave Division Multiplexing (DWDM)
technology that provides an enormous 460 gigabytes per second
(Gbps) of capacity worldwide, has an Asynchronous Transfer
Mode (ATM) fiber node located just a few floors below the
WebTwister NOC.
Qwest comes into Baltimore with an
OC-12 line and plans to upgrade its connection to an OC-48
in the near future. Qwest also has an ATM fiber node just
floors below the WebTwister NOC. Our Qwest connection enables
WebTwister to offer additional redundancy and better routes
to Europe, Latin America and Asia. With our carriers, our
router has up to 150,000 possible routes to send each packet
of traffic.
AT&T is our third Tier One Internet
backbone. AT&T Managed Internet Service provides a reliable,
dedicated, high-speed Internet connection and industry-leading
Service Level Agreements (SLAs). Your business IP services
will reside on AT&T's world-class OC-192/OC-48 IP backbone,
providing you with managed, state-of-the-art hardware and
software, smart routing capability, and continuous performance
monitoring.
Furthermore, because of these unique
connections, WebTwister does not need to link to the Internet
through an OC3 or T3 Telecom circuit. Instead, independent
cables run inside our building directly from the WebTwister
NOC to all three carriers' points of presence. These lines
can handle the bandwidth of a T3 or an OC3 with DWDM. Plus,
they handle several times the bandwidth of an OC3. Whatever
your bandwidth needs may be, WebTwister has the scalability
to meet them.
Industry analysis reveals that 70% of
downtime of over 10 hours with any ISP is caused by telephone
circuit failure. With WebTwister, circuit failure is virtually
eliminated. That's because our NOC is in the same building
as GlobalCenter, Qwest and GTE. There is no phone circuit
between WebTwister and these providers. Instead, there is
a direct connection between our Cisco 7500 routers and theirs.
WebTwister's providers also have peering
connections with other major Tier 1 providers that allow traffic
to be switched to alternate backbones should the need arise.
