The document discusses network design considerations for an Internet data center (IDC) solution. It describes setting up high-performance, reliable wide-area network (WAN) and local-area network (LAN) backbones with technologies like routers, switches, load balancing, bandwidth management and firewalls. The network is designed to securely connect customer systems and applications while providing services like caching, content delivery and virtual hosting.

9. Internet Data Center Environment Remotely-monitored video surveillance safeguards the IDC and its perimeter 24 hours a day, 7 days a week. Hand scanning sensors authorize Internet Data Center clearance by means of biometric recognition. Server racks are reinforced against seismic anomalies with scientifically exact bracing that adjoins both the server racks and the caging environment to a below-floor channel. All IDCs run on clean power conditioned by an Uninterruptible Power Supply (UPS). The UPS provides immunity to energy spikes and surges experienced by the public sector. Backup generators guarantee an alternate power source, providing indefinite hours of additional uptime in the event of a system failure. Multiple HVAC units supplement principal cooling systems for consistent temperature control and maximum airflow. A preferred alternative to conventional fire suppression methods, this system, together with intelligent early detection and backup suppression methods, prevents unnecessary equipment damage and incidental loss of uptime. Internet operations are simultaneously monitored 24 x 7 within each Internet Data Center NOC (Network Operations Center) and from the Exodus Response Center IDC access, 24 x 7 security monitoring and incident management are controlled by on-premises security officers. Alarms are monitored 24 x 7 for rapid incident resolution. Electronic motion sensors detect and react to movement around the perimeter of the IDC and within its interior. .
