The network
operations center (NOC) of GayWebHosts.com 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 our 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.
Uninterruptible
Power System
To guard against local power failures, we have 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 backup
systems in place, we can keep our network up and running indefinitely
without relying on external power.
Industrial-Grade
Air Conditioners
The NOC has two Liebert ten ton industrial air conditioners, which condition
our computer rooms and operations center. Our computer room is kept at
an optimal temperature of 65 degrees fahrenheit.
Custom
Web Servers
The web servers are custom-built industrial machines designed for a 24/7
web serving environment. All servers are equipped with dual redundant
450-watt power supplies, hot swap Seagate Baracuda/Cheetah drives and
force-filtered cooling systems. In addition, the NOC is equipped with
an inventory of identically configured, burned-in standby servers.
Force-Filtered
Server Cooling
All of the 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 which circulate
this purified air. This constant introduction of clean air into the case
creates a positive pressure environment ensuring dust and particles remain
outside of the server.
Hot
Swap Seagate Drives
The drives and drive bays of all the servers are constructed
from high-grade aluminum, and rest in shock mounted drive cages, which
adds to the durability of the hardware. The drives proudly feature the
lowest failure rate in the industry.
In the event
of a server failure, these swappable drives can be pulled and immediately
installed in a standby server enabling your site to be back up and running
within moments.
Redundant
Hot Swap Power Supplies
Each server employs dual-redundant hot swap power supplies. If
a power supply were to fail, the server would continue running with power
from the alternate supply. Meanwhile, alarms would alert a technician,
who would quickly restore redundancy. In the meantime, servers and client
sites would experience no downtime.
Directly
Connected to Three Internet Backbones
The NOC, located in Baltimore, Maryland, is fed by GlobalCenter
(GC), Qwest Communications and GTE through three separate bandwidth-on-demand
connections which enter Baltimore in our building. We are directly connected
to the Internet through these services, so there is no T1 or other intermediate
service to go wrong--ever!
GC, a Tier
1 provider whose 13,000-mile fiber optic network and Dense Wave Division
Multiplexing (DWDM) technology provide 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 NOC.
Qwest comes
into Baltimore with an OC-48 line. They also have an ATM fiber node floors
below the NOC. The Qwest connection enables us 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.
Genuity, a
division of GTE, is the third Tier One Internet backbone. Genuity provides
excellent network performance as a result of their high-speed peering
arrangements with other Tier One Internet backbone providers. The GTE
global network delivers customers directly onto the Internet via a high-speed
connection to its private, super-capacity backbone, including 17,000 miles
of fiber and OC192 capacity. It is comprised of more than 800 U.S. local
access points and approximately 1,500 international local access points
in more than 150 countries.
Network
Redundancy
The NOC uses intelligent end-user routing software called Border Gateway
Protocol (BGP), between Qwest, GC and GTE, who use the same protocol.
BGP identifies which path is the most efficient for each data packet and
then routes the packet to its destination on the fastest path. This increases
the speed at which web pages sent from our NOC arrive at their destination.
Studies have
shown that the most common reason for downtime is circuit failure on Tier
1 provider backbones, the major data highways. To guard against this potential
problem, we have three Tier-1 providers. If one experiences problems,
we can route traffic down the other one. Furthermore, because we are OnNet
with GlobalCenter, Qwest and GTE, we share their digital distribution
architecture, which includes private peering network connections to major
Internet carriers such as MCI, Sprint, UUNET, EUNET, AT&T, AOL, Best,
Erols, @Home, IBM Advantis and others. These private peering arrangements
allow our NOC to exchange packets of data with every major backbone carrier
in a one-to-one environment quickly and efficiently.
In addition,
GC has high-speed links to eight public exchanges including both MAE East
and West and several NAPS. Through these public exchanges, visitors have
the ability to reach your site, no matter where they are coming from on
the Internet.
Network
Reliability
Industry analysis reveals that 70% of downtime over ten hours with any
ISP is caused by telephone circuit failure. Since our NOC is in the same
building as Global Center, Qwest and GTE, circuit failure is virtually
eliminated because there is no phone circuit between us and our providers.
Instead, there is a direct connection between our Cisco 7500 routers and
theirs. The providers also have peering connections with other major Tier
1 providers, which allows traffic to be switched to alternate backbones
should the need arise.
Raw
Performance Equals Low Latency/High Throughput
Too often providers operate their networks at three to four times responsible
capacity. As a result, their corresponding transfer times reach over 300ms.
Our NOC's network daily average is 27% of its capacity, with midday peak
spikes reaching only 33% capacity. Our NOC guarantees clients will be
carried off our network in less than 80ms over a five minute average at
any time of day or night.
NOC
Security
The NOC provides a full range of security services to insure
the safety and integrity of mission critical data. As more businesses
harness the power of the web, reliable and secure public communication
is an ever increasing need. We stand at the forefront of providing clients
with secure communication solutions.
Firewalls
A firewall is a security device that secures the server from
possible attacks and is placed between the server and the Internet to
moderate and document requests for data access according to a predefined
set of security policies. Every server comes equipped with a firewall,
which is built and managed by the NOC security engineers. Our NOC staff
is managed by a network security engineer with over fifteen years of experience
in telecommunications cryptography. In addition to the individual firewall,
our entire network is secured through a circuit level firewall, providing
one more level of security for mission critical data.
Security
Monitoring
To ensure the integrity of our customers' web sites, we proactively
monitor system processes on each server as well as across our entire network.
These monitoring programs are designed to halt and report all intrusions
to the system and provide our customers with the peace of mind they need
to conduct secure business transactions from our servers.
NOC
Automation
GayWebHosts.Com operates scripts that ping the servers every few minutes
to make sure that each server is accessible from within and outside our
network. If the server cannot be pinged, the script sends an e-mail and
pages our system engineers immediately for rapid correction.
Automated
Web Server Monitoring
Our tools monitor the Apache web server to ensure that it is up and serving
pages. Every two minutes, we send a test page to the http daemon. If it
does not respond, our script will reload the daemon. Then two minutes
later it will send a test page again. If there is still no response, then
the reload/test scenario repeats itself. After two attempts, a technician
is contacted to take the remedial steps needed to make sure that servers
are fully operational.
Automated
Memory Monitoring
This monitor makes sure that no process takes up more than a certain percentage
of your available memory. If a process consumes more than the maximum
allotment, it is temporarily killed off and the situation is reported
to the NOC staff.
Automated
Port Monitoring
The NOC actively monitors all commonly used ports to make sure that they
are open, and to verify that they are actually passing data. The script
does this by requesting data. If the port does not respond, it is restarted
by the monitoring tool.
Automated
External Monitoring & Server Control
All of the servers and the network are monitored externally. In addition
to the internal scripts described above, we use off-network servers to
provide corrective action, notification and coverage for maximum protection
of service delivery. Using these off-site machines gives us the ultimate
guarantee that we can provide the uptime and reliability promised to our
clients.
Automated
Backups
The NOC provides automated daily backups on all servers: a daily incremental
back up and a weekly full backup. The full backups are placed onto tapes
and are stored for two weeks while the incremental backups are stored
onto disk and kept until the next full backup is performed.
