| Network infrastructure & architecture |
Cyberpark Internet's advanced Network Operations Centre (NOC) in Washington, DC is staffed by highly experienced Systems & Network Administrators 24 hours a day, 365 days a year, and features
heavy-duty UPS (uninterrupted power) and AC systems.
The local network is arranged in three logical segments:
Core - redundant Cisco 7206 VXR NPE-300 routers connected to the Internet via multiple full-capacity 45 Mb/s DS-3s; running the full BGP4 protocol.
Distribution - a high-end Catalyst 5508 RSM master routing switch that distributes access to the physical and virtual LANs.
Access - Catalyst 2924XL EE switches to which all servers are connected. Each and every server gets a full 100Mb/s full duplex port to the access layer.
Our network does not use any 10Mb/s switches, or any hubs - at all. It is completely Fast Ethernet (100 Mb/s, for access) and Gigabit Ethernet (1000 Mb/s, for core and distribution) based.
Both internal and external network provides multiple, redundant, paths. The network also features a 1.9TB (terabyte) robotic tape autoloader library backup system, as well as multiple RAID-based
high-volume backup units.

| Physical network infrastructure |
Currently, Verizon provides our fibre-optic uplink through a dedicated OC-12 (622 Mb/s) circuit. Additionally, we are installing a Unidirectional Path-Switched OC-12 SONET Ring with MCI WorldCom's
MFS, construction of which began in January, 2001.
The UPSR OC-12 SONET ring consists of four redundant OC-12s traversing two separate paths, thus providing the ultimate in reliability and performance. Even if two of the lines are cut, the
OC-12 ring is still operational, with less than 50 ms (0.05 second) self-healing restoration time. The OC-12 SONET ring is integrated as a direct part of MFS' own DC metro-area OC-48 SONET
ring (not mux'ed), which assures absolute 100% uptime.

| Advantage of our network |
The DC area is an ideal location for a NOC. A very large portion of the world's Internet traffic passes through here, and the area is not subject to earthquakes, tornadoes, floods or other
natural disasters.
We are located at the true heart of the Internet, and in a very safe and secure area. This central location ensures optimal connectivity, speed, and routing, minimizing the number of hops -
and thus the chance of any problems. We are right by MAE-East and a great number of private peering points. All providers have multiple, redundant routes into DC. This is further built upon
by our redundant connectivity to multiple Tier 1 providers via separate DS-3s, terminating at diverse locations in DC, Maryland, and Virginia. We are redundantly set-up Internet connectivity
wise (multiple backbone connectivity providers), as well as physically (in terms of fiber optics, lines via different LECs terminating at diverse locations, and a dedicated UPSR OC-12 SONET
ring on order with MFS).
Cyberpark Internet's network design and operations ensure the very best connectivity, speed, and reliability possible: 100% network uptime, no packet loss, and under 3 ms low latency connection
to Tier 1 backbones -
guaranteed by our industry-leading SLA.

| Multi-user hosting server set-up |
All of our Unix multi-user hosting servers are a minimum of:
Sun Ultra10 Dedicated High-Duty Internet Server with 512MB RAM, 9GB disk space, and setup consisting of the latest versions of Solaris (Unix) operating system, Sendmail, ProFTPD, Apache, and
any other appropriate and standard software.
As required by our clients and traffic trends, most servers will be Ultra-10s or better, will have more RAM, more storage space, and all will have much more custom software installed.
All of our Windows NT/2000 & RedHat Linux servers are a minimum of:
Heavy-duty, custom built, double processor Pentium III PC server, with 512MB of RAM, 9GB disk space, and set-up consisting of the latest version of Windows NT or Windows 2000 operating system,
MS IIS server, and any other appropriate and standard software.
As required by our clients and traffic trends, most servers will have Pentium III processors, more RAM, more storage space, and all will have much more custom software installed.
For Unix, we use superior Sun Internet servers running the robust Solaris operating system, that ensures 99.9%+ uptime including regular maintenance. For Windows NT/2000 and RedHat Linux we
use high duty, custom built especially for continuous server use, PC servers running Windows NT Server 4 or Windows 2000 Server, or RedHat Linux, respectively.
