Computer
Integrity leverages Dialtone's Network Operations Center (NOC)
infrastructure support which provides 24 x 7 monitoring of our servers, network
status and connectivity to upstream backbone providers. Our
NOC technicians identify potential issues and provide resolution
before any problems occur.
Both our Servers and our multiple backbone connections are monitored
around the clock. Our custom made monitoring and control software
alerts our network support personnel whenever a problem with a
Server is detected. Remedial actions include further testing
and identification of the problem, process termination and restart,
soft reboot or hard reboot. Often, a problem with the Server is
corrected within minutes from the time it occurred.
| With
ready access to servers from the monitor room "NOC," support
and administration personnel continually monitor the systems,
answer customer questions and quickly troubleshoot any problems.
Computer Integrity has taken many steps to ensure
continued and uninterrupted operation.

Redundant backbone connections with different backbone providers
ensure high level of network connectivity (over 99.99%), while
UPS, emergency generators, an inventory of drives, memory chips
and other hardware components allows us to get Servers running
quickly in case of hardware failures.
To ensure maximum connectivity and minimal downtime, we use redundant
systems. This includes our Cisco routers, switches, and sub master
switches, our power system (three diesel fueled generators in
addition to our regular grid electrical power), and our backbone
(multiple DS-3 with 5 providers on a dual OC-12 smart ring (shared)).
Each server is connected to an uninterruptible power supply, protected
by a fire suppression system and multiple air conditioning
(HVAC) systems. We keep a ready supply of drives, network cards,
processors, motherboards and every piece of equipment that has
even a remote chance of failure.
Instead
of standard RAM, we use PC100 SDRAM with ECC (Error Checking And
Correcting), that detects and corrects single bit errors. The
ECC RAM eliminates server crashes due to corrupted data in memory,
allowing maximum stability and uptime.
Network Security
Among the measures we take to thwart attacks and ensure
network availability are:
- Redundant
Cisco 7513 Routers, capable of routing up to 4.2 Gigabits of
total traffic,
- Multiple
DS-3 lines connecting us with five different Tier-1 providers,
use of a Sonet ring network architecture,
- Fully
switched network to prevent the packet sniffing of TCP connections,
- Resistant
routing to hold network attacks at bay by configuration,
- Tracking
systems to trace malicious acts (attacks, spamming) to their
sources.
We
provide 24 x 7 managed network monitoring service, and respond
within minutes to server failures, attacks or Internet backbone
problems. As a result, we have minimized and nearly eliminated
the adverse effects of distributed denial of service (DDoS) and
other attacks, and our network uptime is over 99.9%.
Preventing attacks can be far easier and less costly than responding
to them after the fact. To that end, we discourage the use of
IRC bots and shell accounts on our servers, and encourage our
customers to use secure shell accounts rather than telnet to communicate
with their servers.
Site
Security
The
NOC lobby is protected around the clock, seven days a week by
building security personnel, a closed-circuit TV system with 16
cameras inside and outside the premises, and video tape recording.
Access to the data center area is individually authenticated,
so those entering the building must pass through turnstiles.
To get to a server with customer data on it, an intruder would
have to pass through numerous points of authentication or identification
via key, camera, or human.
The internet security system provides a record of who has entered
a room, and at what time, thus allowing us to audit access to
the systems.
