Our Network
The backbone network
SAVVIS has engineered its network around a single platform - AS3561 - which enables one global IP backbone, rather than regional Autonomous Systems stitched together. That means that once data gets on the network, it’s a single BGP hop to the global network node nearest its destination. This minimizes the number of router hops and reduces the risk of downtime when traffic has to traverse multiple networks.
Featuring bandwidth-on-demand connections with one of the primary Internet backbones in the United States, allowing us to offer multiple fast OC-192 & GigeE connections, one of the fastest, most reliable connections available today.
Some of our international competitors support services on multiple continents through joint ventures and partnerships. SAVVIS owns its own network - there are no joint ventures that may affect performance and support.
A single AS means:
- Customers are only one hop away from content hosted on the SAVVIS network
- Access to all of the routes on the Internet
- A single end-to-end Service Level Agreement
Network features include:
- Based on industry-leading Juniper core routers and Cisco equipment specifically designed for the needs of Tier 1 "carrier-class" customers
- OC-48/OC-192 backbone trunks, supporting MPLS protocol
- AS3561 is consistently rated over time as having the lowest latency, lowest packet loss, and highest reliability
- SAVVIS firmly segregates Layer-2 (transmission) and Layer-3 (routing)
- Layer-2 is ATM-based for traffic management
- Core network is designed for “zero” packet loss
- SAVVIS is moving to more efficient MPLS Layer 2 protocol
The graphic below illustrates our USA peering locations. SAVVIS primarily peers in Chicago, Seattle, Washington DC, Atlanta, Dallas, Dubai, New York City, San Francisco.

- Generators are tested on weekly basis under load
- Tanks are kept at least 80% full at all times
Two utility feeds from independent substations
- Diverse paths to the building
- Feeds to building are encased in concrete
- Fed from two independent substations
- Separate transformers fed from both utility sources for redundancy
HVAC chiller systems
- Hosting space HVAC system includes (16) AHUs and (16) ACCUs manufactured by Trane
- AHUs are DX type and located in the mechanical mezzanine; the ACCUs are located on the roof
- There is adequate capacity to withstand a HVAC unit failure or an entire bus failure
Cooling is provided by both overhead and under floor air
- HVAC systems have wetted media for humidification, VFDs for each supply fan, exhaust fans to control building pressure, and economizers to utilize cool outside air
- Separate Dectron outside air handling units provide conditioned air for the hosting space
- UPS Room cooling is provided by Trane RTUs in a N+1 configuration
- Node room cooling is provided by Liebert DX CRAC units in a N+1 configuration
Network facilities - Main Node Room
- Multiple fiber providers for diversity - provides diversity and redundancy
- Each vendor can deliver additional bandwidth capacity with minimal turn-around time
- Can be delivered using existing ‘lit’ fiber
- Fiber pathways into the Data Center are truly diverse
- Fiber enters building in steel conduit from multiple points in the building
