Security
Restricted access to the Network Operations Center is monitored by qualified personnel 24 hours a day, every day. Visitors and clientele are only allowed on-site if escorted by Data Center staff. The entire Data Center is monitored, ensuring prompt response and thorough coverage to fire or security alarms. We supply all our Data Center customers with advanced firewall, encryption, intrusion detection and other security measures. Nexus maintains a full digital video surveillance system of the Data Center, with full on-site and off-site recording.

Failsafe Power Supply
Our Data Center currently has 800amps 3-Phase AC power currently available from PP&L™ (Pennsylvania Power & Electric). The facility is currently backed up and protected by a 160KVA Powerware™ 9135 facility-wide UPS (Uninterruptible Power Supply) system. In a very rare case of utility outage, our Cummins™ 250KW deisel generator starts automatically, taking over for the UPS systems and supplying all necessary power for the facility. The generator interfaces to the power grid thru a Cutler-Hammer™ automatic transfer panel. The generator is powered by a 500 gallon fuel tank, capable of running without refueling for approximately 80 hours.

Backup Systems
Nexus automatically provides backup data services to all shared hosting solutions clientele. Services are also optionally available to all dedicated and co-location clientele. Nexus utilizes backup hard drives on each individual server to store backups. Linux systems store zipped copies of server system files and client data files, for simple server rebuilding. Windows™ NT/2000/2003 servers store full image backups (identical copy of operating system and data at time of backup), for full system restoration. Off-server and off-site backup services are available as well.

24x7x365 Monitoring
The Data Center uses industry-standard SNMP (Simple Network Management Protocol) and provides round-the-clock monitoring of all hardware, including routers, switches, UPS systems, and servers. The Data Center also monitors power, environmental factors (such as temperature and humidity), generator status, and network connectivity. All critical services/ports are monitored, including FTP, HTTP, SMTP, HTTPS, SSH, TELNET, and POP3. We provide network monitoring of the Local Area Network, Internet connectivity (all routers, switches, and wiring), and the Internet backbone via MRTG. Our close and constant communication with our upstream backbone providers ensures that our customers have constant access to high-performance Internet connections. Failure on any monitoring service results in and alerting our staff paging system.

Hardware
The Data Center utilizes ONLY top name brand hardware. The network is centered on a Cisco™ GSR12000 Border Routers, and Cisco 7206VXR Core Routers, connecting via Gigabit Ethernet to the Hewlett Packard™ Procurve™ 4108GL & Cisco™ Catalyst™ primary switches. Hewlett Packard™ Procurve™ managed switches comprise the power and stability of the network, operating at 100mbps switched ethernet speeds. Hardware utilized in the facility is comprised of name brands, including the following: Intel™, Asus™, Abit™, AMD™, 3Com™, Hewlett Packard™, Adaptec™, Cisco™, Tekram™, Kingston™, Micron™, Crucial™, IBM™, Maxtor™, Western-Digital™, Seagate™, Quantum™, Fujitsu™, Realtec™, Belkin™, & Lucent™. APC™, Tripp-Lite™, Compaq™, & Liebert™ UPS Systems provide the power backups, along with a Cummins™ generator system. Facility monitoring is provided by a Panasonic™ WD-500 Digital Video System over Sony™ & Panasonic™ CCTV cameras.

Software
The Data Center utilizes the Red Hat™ Linux operating system on the majority of servers present. Red Hat™ Linux is a highly configurable system, and well known for speed and stability. Red Hat™ Linux servers have been documented to remain operating for up to one year at a time without even requiring a reboot. The Apache™ Web Server nicely compliments the Red Hat™ Linux Operating System. The majority of remaining servers operate on the Microsoft™ Windows™ NT/2000 operating systems, with Internet Information Server™ Web Server. Microsoft™ Windows™ NT/2000 provides a system that simplifies database, application, and visual effect programming. Nexus also supports FreeBSD™, Mandrake™, Slackware™, Turbo Linux™, & Debian Linux™.

Connectivity
The network is connected via Gigabit fiber connections to Verizon™ (Formerly Bell Atlantic PA), PPL Telcom™, (a sub-division of Pennsylvania Power & Electric™ - PPL™) and Commonwealth Telephone™ (CTSI™), NorthEast PA's 2nd largest Telco. Our transit is provided via Gigabit Ethernet (1000mbps) from Verio™ (http://www.verio.com), Global Crossing™ (http://www.glbx.com), Cogent™ (http://www.cogentco.com), and XO™ Communications (http://www.xo.com). For redundancy, we are currently running BGP4 (border gateway routing protocol) to maintain the speed and uptime. If one backbone line goes down, it will balance the load to the other(s). If one line gets congested, it will load balance the traffic.
