Xandr currently runs five datacenters: LAX1 in Los Angeles, NYM2 in North Bergen, NJ, AMS1 in Amsterdam, the Netherlands, FRA1 in Frankfurt, Germany, SIN1 in Singapore. We feel that it is important to have multiple, geographically disparate datacenters that each functions as a self-contained entity with its own set of equipment. This way you can set up your network with the following benefits:
- Speed and the reduction of latency: Signals travel fast, but travel time can still add up. With datacenters on each coast and in Europe, connection times can be reduced when users are directed to the nearest datacenter via our global load balancers.
- Redundancy: Within each datacenter our servers are clustered so that any one machine failure will not impact access to our service or ad serving. If a datacenter loses connectivity to the internet, all traffic will be automatically routed to the others. Our UI, API, database and reporting infrastructure is also redundant such that we have a presence in at least two of our four data centers.
- Disaster recovery: You can automate data backup so that in an extreme event, such as a blackout, fire, natural disaster, or terrorist event, your data remains intact. In case of a disaster, all traffic can automatically be rerouted.
We are extremely selective in our colocation providers, and we have chosen to work with world-class datacenter providers; CoreSite (CRG West) in Los Angeles and Equinix in the New York Metro region and the Netherlands. Each of our datacenters has redundant power and network feeds including auxiliary power in case of an outage.
CoreSite is a premier colocation and datacenter management company headquartered in Denver, Colorado. It is one of the largest managers of carrier-neutral datacenters in the United States with ten such datacenters in eight major metropolitan markets. CoreSite now manages over 2 million square feet of datacenter and colocation space, including over 170,000 square feet at the world renown One Wilshire Building in downtown Los Angeles. CoreSite is a wholly owned subsidiary of The Carlyle Group, a global private equity investment firm.
Equinix is the largest global network-neutral datacenter and Internet exchange services company in the world, with centers in 18 key markets across North America, Europe, and the Asia-Pacific and a total global footprint of more than 3 million square feet.

Floor Layout and Network Cabling
All racks are laid out in a hot/cold aisle configuration. This means that cold air is dropped down on the intake side of servers and exhausted out the back. This helps keep server temperatures low reducing failures and increasing hardware lifetime.
