At JDK Hosting, we take pride in the service we provide to our customers; therefore, we ensure our equipment and network are the best in the business. We do not cut corners when it comes to our hardware or network.

Our network is compromised of servers located in the Caro.net, Saavis and Databank data centers. Specifications for our network and each datacenter can be read below.

Overview

Our network is designed to be fully redundant and self healing from top to bottom. The only single possible point of failure is the connection to the physical server which limits any risk to a single rack or server. Each Foundry EI-4802CF access switch dual uplinks to a Foundry FESX-424 allowing for local layer 3 switching, policy assignment and egress DoS protection. The FESX provides redundant service by utilizing VSRP/VRRP ensuring that both layer 2 and layer 3 traffic has an alternate path in the event of a failure.

Each FESX connects via 10GbE to one of a paired Force10 E600's which act as layer 3 aggregation routers. In addition to the direct connections to the E600's, each FESX connects to its hot-spare through a dedicated 10GbE connection ensuring that in the event of a physical network cable/fiber cut the device does not need to degrade its master status and can continue passing traffic through its hot spare thus limiting the amount of actions taking place in the event of a minor failure.

The E600's interface with multiple Juniper M20's which peer with our bandwidth providers via multiple redundant OC-48 connections providing a maximum throughput of ~22Gbps. The E600's and the M20's communicate internally via iBGP allowing for extensive route mapping and traffic shaping helping us to provide you with the fastest connections and least latent path possible.
