Sustainable Hosting has Tier 1 bandwidth providers, including Peer 1 Network, SBC, Allegiance, and Time Warner, built on a Cisco powered network. We guarantee 99.9% uptime and will provide you credit for any downtime experienced due to our network.

Cisco Powered Network
Every Sustainable Hosting server is connected to a 100% Cisco Powered Network. Using enterprise-class Cisco networking gear, all routers, layer-2 switches, and layer-3 switches are tested in labs prior to deployment to ensure stability and interoperability.

Redundant High Bandwidth Connectivity
Using multiple Tier 1 Service Providers, Sustainable Hosting leads the hosting industry with our 99.9% uptime guarantee, ensuring the highest degree of security against network downtime and the fastest possible data transfers.

Bandwidth Utilization
It is a common misconception that the amounts of bandwidth (size of the pipes that carry the data) differentiate web hosting companies. In reality it is not only the size of the pipes that matters, it is the utilization levels. The utilization of our Internet connections is vital to a network's ability to transfer data without packet loss or latency. Sustainable Hosting aims to keep all connection usage below 50% to avoid any connectivity problems.

Dynamic Routing
Sustainable Hosting runs the Border Gateway Protocol (BGP4) for best case routing. The BGP4 protocol is a standard that allows for the routing of packets of information sent out from our network. Each packet of information is evaluated and sent over the best route possible. Because of our redundant network architecture, packets may be sent via alternative routes even if they are being delivered to the same end user. Should one of our providers fail, packets leaving our network are automatically redirected through another route via a different provider.

Network Security
The Sustainable Hosting network is a fully switched network. Traffic destined for a website hosted on a server is sent only through switching equipment necessary to deliver the information to that server. This minimizes the risk of someone sniffing or capturing traffic being sent across the network. Furthermore, Sustainable Hosting vigorously prosecutes persons who generate malicious attacks on our internal network. Our data centers, located in San Antonio, Texas and northern Virginia, have been built from the ground up to provide powerful connections to our carriers to ensure that we meet our 99.9% uptime guarantee.

Carrier Class
Our facilities are carrier-neutral sites and are built completely on computer-grade raised flooring; it is built for hosting with redundant fiber entry points.

Regulated Climate Control
The data centers' HVAC (Heating Ventilation Air Conditioning) systems are N+1 redundant. With full particle filtering and humidity control, the environment are maintained at a cool 68 degrees to ensure a comfortable environment for your server.

Power Systems
Sustainable Hosting is not reliant upon the local power grid to guarantee maximum uptime. Our on-site, auto-switched power generator, and centralized UPS systems provide power conditioning and ensure uninterrupted data center operation. Additionally, the generators are regularly tested to ensure that it will continue to function in the event of an emergency.

Datacenter Security
Our data centers are physically isolated from everyone but level three technicians. Public access is strictly forbidden. Access to the floor the datacenter resides on is restricted and completely locked down.
