The Linode Network Infrastructure
We like to share, in general. But not when it comes to bandwidth. That's why we built a completely switched network using only the
highest quality equipment and network providers. Each Linode connects to our world-class network, for some serious bandwidth.
Our internal network uses 100% Cisco networking equipment. Every machine on our internal network has a switched 100 Mbps Fast Ethernet
connection to our Cisco switching equipment.
ThePlanet Internet Services - Dallas, TX
Host servers host1 through host8, and host27 and up are located at ThePlanet's Dallas, Texas data-center facility.
From there, our switches connect to ThePlanet's core network via multiple 100Mbps Fast Ethernet links (using HSRP), again for load balancing and redundancy.
Through ThePlanet, we have the following Carrier Backbone connectivity:
- 1 Gbps Direct Fiber - MCI/UUNET
- 1 Gbps Direct Fiber - Time Warner
- 1 Gbps Direct Fiber - Level 3
- 1 Gbps Direct Fiber - Verio
- 1 Gbps Direct Fiber - Global Crossing
- 2 Gbps Direct Fiber - Allegiance Telecom
- 2 Gbps Direct Fiber - AboveNet
- 1 Gbps Direct Fiber - Sprint
- 1 Gbps Direct Fiber - AT&T
- 1 Gbps Direct Fiber - Broadwing
ThePlanet has provided Linode.com with a 100% Network and power uptime Service Level Agreement (SLA).

Our network architecture utilizes the Enterprise routing and switching engines from Juniper and Cisco. We utilize Juniper M20 routers as border routers, Cisco 6500 series switches in our distribution layer and Cisco 6500 switches in our aggregation layers, and Cisco 3500 and 2900 series switches at the customer layer. Our network is fully meshed and redundant with 10 backbone providers. Our current network consists of UUNet (GigE), Sprint (GigE), Level 3 (GigE), Global Crossing (GigE), Verio (GigE), AT&T (GigE), Time Warner (GigE), Allegiance Telecom (2 x GigE), Broadwing (GigE) and AboveNet (2 x GigE).

| Our self-healing network architecture virtually eliminates a single point of failure. In addition to our own backbone, we also purchase backup transit from multiple providers in multiple locations to ensure that your data will arrive via the shortest possible routes. Because of our backup transit and the many international peers, our network maintains the shortest routes for sending your data all over the world. On an ongoing basis, we are negotiating with the top fiber carriers for new routes, additional backup transit providers, and we are signing on new peering relationships.

Remote Console and Power Management
Each and every piece of networking equipment, whether it be a switch, a server, or some other device, is
connected to our networked Baytech RPC Remote Power Control units. All our gear is also connected to Baytech DS series remote console
access units. This provides us with complete out-of-band network and dial-in access to our equipment at the power and console level.
Simply put: we can turn on/off the power to a server remotely and access the server's BIOS via console access.
We can even do this if the machine doesn't boot properly. This minimizes administration response time.
Linode.com's network and management infrastructure is world-class in performance, reliability, and scalability.
