||Savvis Data Center
The Savvis data center is located in Fort Worth/Dallas, Texas and is in a
carrier grade facility with high security
and every redundancy, disaster or conceivable problem is already planned for.
The Savvis data center houses
Fortune 10,100,1000 companies in its data center along with many government and
other large corporations.
It houses enough servers and enough data passes through its backbone which is
located in the same facility that it is
considered a national entity and will be protected by the national guard in
times of crisis.
The Savvis data center is also a MASSIVE facility with over 250,000 SQFT of DC
floor space available.

AS3561 - The SAVVIS 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
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 SAVVIS Global AS3561 IP backbone has peering connections with 13 Tier 1 US
and five Tier 1 European backbone providers. SAVVIS has built new OC-3 [STM-1]
and OC-12 [STM-4] for a total of 26GBps connections to its largest direct
connect peers, thus providing faster and more reliable access to their networks.
With these enhancements, SAVVIS is able to allocate sufficient bandwidth to each
peer, aiding in effective capacity planning.
In Europe, SAVVIS maintains pan-European private peering connections at LINX,
PARIX and AMSIX operating at STM1 or higher speed with GTS/Ebone, Infonet/AUCS,
UUNET AS703, Teleglobe and KPNQwest/EUNET. Additional European peering
connections are under consideration.
These connections will provide our US customers with direct access close to 100
percent of the global address space and our European customers with direct
access to 90 percent of the European address space. The benefits to SAVVIS
customers include: faster access, minimum AS hops, lowest possible packet loss,
and a better ability to plan for future growth for ISPs that peer with the
SAVVIS IP backbone.
With an aggressive peering plan, including peering agreements with the largest
Tier 1 backbones, SAVVIS is one of the leaders in the industry in finding
efficient ways to route IP traffic through our network and beyond.
With the globalization of the Internet and SAVVIS' response of expanding the US
based IP backbone to a truly global backbone under one AS3561, peering has
become increasingly complex and the established peering policies have been
amended. SAVVIS has formulated a global peering policy to maximize the benefits
of peering to our customers and also provide equitable treatment of our peering
In addition to its peering relationships, SAVVIS has direct transit connections
with over 1,300 ISPs in the US and 100 direct connections to ISP's in over 70
countries. In peering and transit arrangements, SAVVIS' global AS3561 stands for
quality, unsurpassed in the industry.
SAVVIS is a Tier 1 ISP that offers both IP connectivity and e-business solutions
to enable global corporations to quickly reach their desired Internet content.
To offer our customers efficient access to destinations that reside outside of
SAVVIS’ Global IP Network, peering has been established at select major cities
where our backbone nodes are present. In the USA, we have established peering
relationships with the four other Tier 1 ISPs: AT&T (ANS), Genuity (GTE
Interlink), UUNET (WorldCom), and Sprintlink.
As is the case with all Tier 1 ISPs, SAVVIS is prohibited from peering directly
with any network outside the USA; however, our 270 transit relationships with 80
countries will provide the customer with excellent connectivity to overseas
markets. We peer with five pan-European Regional Tier 1 networks including:
UUNet (WorldCom), Ebone (GTS), AUCS (AT&T and Infonet), EUNET (KPN/Qwest), and
France Telecom (which includes Global One and Equant), providing SAVVIS
customers access to 90 percent of all European routes. In Asia, SAVVIS is
establishing similar peering connections in Japan to provide similar route
coverage. Once these peering arrangements are in place, no other Tier 1 ISP will
be able to match SAVVIS’ global peering coverage.
