Core Network & Backbone Connectivity
|
Our fully redundant core network and backbone connectivity
is unsurpassed in its efficiency and performance. With eleven
separate sites, located in five different states on both coasts
and central US, and fully redundant architecture out of all of our data centres, our network offers extremely low latency,
no packet loss, and, best of all, direct connectivity to all
major global tier 1 backbones and other major networks & ISPs.
This unique combination provides a superior network infrastructure
with an unmatched quality of service.
Our
core network consists of eleven (11) sites, located at five states,
coast-to-coast.

Our
network is legacy-free and only utilizes the latest in Cisco
internetworking equipment. The network is fully redundant
at each and every level possible, there being no single point
of failure. The network is fully fault tolerant and able to
withstand a major disaster.
Physical
Network Infrastructure
The
physical layer of our network consists of a number of interconnected
private OC-192 SONET rings. Our Virginia & DC multiple OC-192 SONET rings are operated
by Level 3 (former Looking Glass Networks) and Cox Communications, while in Seattle we use OnFiber, Q.West,
ELI & Integra Telecom redundant SONET rings. Our transport between Ashburn,
VA, Chicago, IL, Palo Alto, CA and Seattle, WA is provided
over redundant Level 3 and Global Crossing SONET rings, while to New York we are
using Level 3 (former Looking Glass Networks). All of our fibre carriers are
financially healthy and well known major telecoms
with proven 100% uptime and reliability (Looking
Glass Networks, Level 3, Cox Communications, OnFiber, Q.West, ELI, and Integra Telecom).
The OC-192 SONET rings consist of two redundant OC-192s
traversing two separate paths and having two diverse
routes to our facilities, thus providing the ultimate in reliability
and performance. Even if both of the lines are cut at any
point, the SONET ring is still operational, with less than
50 ms (0.05 second) self-healing restoration time.
The multiple private SONET rings provide us the ultimate in
reliability: no downtime even in the case of a major fibre
cut in the area (due to separate paths and multiple fibre
carriers).

Network Maps of our Tier 1 Backbone Providers:
|
|
| Traffic from each one of our sites considers all the outgoing routes
- including routes through all the other sites - weighted for physical distance, reliability, performance and latency, and
picks the most direct, lowest latency route available to the destination.
That is, all the packets take the most direct, fastest, way out and have
a full BGP selection of all the transit providers and peers at all the sites,
not just the transit/peering lines present at that particular site. The
network is fully inter-connected and meshed. |
| |
|
|
| Extensive
Peering:
In
addition to buying commercial transit from the world's major tier 1 backbones,
we also have an extensive peering network established. Peering is the
process whereby one network provider, such as us, connects to another
one directly -- bypassing the "middlemen" (intermediary networks).
Peering provides a more direct, faster, and shorter route than transit
by bypassing other third-party networks, resulting in considerable performance & reliability
gains. However, very few networks engage in peering, as typically a coast-to-coast IP backbone
is required for a network to qualify for peering (so only very large national or International
Internet networks even qualify to peer), and it is considerably more costly and
time-consuming to maintain many 100s, if not 1000s, of peering connections, vs. just a few transit links.
We, however, always go for the best and invest the time and the resources necessary in order to ensure
that our customers enjoy performance that is truly "Ahead of the Rest."®
We
have a large number of peer sessions (over 500), composed of major national
& international backbones, ISPs and content providers, at the Equinix
Exchanges (IBX'es) in Ashburn, VA and Chicago, IL, at NYIIX in New York,
NY, at PAIX in Palo Alto, CA and Seattle, WA, at the SIX in Seattle,
WA, and at Any2 in both Los Angeles, CA and San Jose, CA, in addition to a number of private peering inter-connects. A
partial list of our peers follows, below. Note that new peers are added
on a regular basis, so, the list below may not be complete and up-to-date.
For redundancy and optimal performance, we peer with most peers at multiple
locations.

SLA guarantees that.
Further
Advantages of Our Network
The
northern Virginia / DC area is an ideal location for a data centre.
A very significant portion of the world's Internet traffic passes through
here, and the area is not subject to earthquakes, tornadoes, floods
or other natural disasters. With two data centres in Northern Virginia,
and a West Coast data centre in Seattle, WA, we are able to provide
the ultimate in multi-site, geographically-dispersed, mission-critical
hosting services.
We
are located at the true heart of the Internet, and in a very safe
and secure area. This central location ensures optimal connectivity,
speed, and routing, minimizing the number of hops - and thus the
chance of any problems. We are located right beside a great number
of of private and public peering points, in one of the most densely
and best connected areas in the world, including directly peering
at the Equinix Exchanges (IBX'es) in Ashburn, Virginia and Chicago,
Illinois, at the NYIIX in NYC, New York, at PAIX in Palo Alto, CA
and Seattle, WA , at the SIX in Seattle, WA, and at Any2 in both Los Angeles, CA and San Jose, CA. All providers have
multiple, redundant routes into the DC/VA area. This is further
built upon by our redundant connectivity to multiple Tier 1 providers
via separate circuits, terminating at diverse locations in Virginia
and the District of Columbia. We are redundantly set-up Internet
connectivity wise (multiple backbone connectivity providers), as
well as physically. In terms of fibre optics, we have multiple private
OC-192 SONET rings with multiple financially-healthy fibre
providers, taking different physical paths.
Likewise
in Seattle, we are located in a stable and level area (ground level
of a well-built single story facility), providing the best resistance
to earthquakes, and have multiple diverse-path fibre transport circuits
with OnFiber, Q.West, ELI, Integra Telecom and Sabey. Seattle is one of America's best connected
high-tech cities, and is an excellent base for high-performance,
reliable Internet connectivity, and provides some of the most reliable
power found anywhere.
We
have built our facilities in the best possible areas for Internet
connectivity and electrical utility reliability, and then further reinforced them with redundancy in
all the possible forms. For example, we are able to offer multiple location
hosting with the advantages, such as low latency and direct connectivity of the same IP network, yet the redundancy
and security of three separate Data Centres in two different states, over 2500 km physically apart (Virginia & Washington state).
Under 5ms (0.005 second), 10 miles, apart DCA2 and DCA3 are available for ultra low-latency dual-location hosting needs,
while DCA2 and/or DCA3 plus SEA2 add up to a 2500+ miles apart fully geographically redundant hosting, just
some 70ms (0.07 second) apart, on the same reliable & secure coast-to-coast IP network.
To
ensure the best routing of our customers' data, in addition to peering,
we also pay for commercial top-priority transit network capacity
to our tier 1 backbone providers and have full burst capacity available
at all times on all circuits. Thus we receive the highest level
of service, including 99.99% or 100% uptime and no packet-loss guarantees,
from all our connectivity providers. 90%+ of traffic from us to
end users only passes over one or two backbones on its way to reaching
the end destination. In addition, we are committed to under 50%
network capacity utilization at all times; we ensure that our network
always has double the capacity it needs, even at peak hours.
Furthermore, our core network routers always have not only dual power supplies,
but, where available, power feeds to each power supply from a different power grid & UPS system, thus
ensuring the ultimate in reliability.
Our
network design and operations ensure the very best connectivity,
speed, and reliability possible: 100% network uptime, no packet
loss, and under 3 ms low latency connection to Tier 1 backbones
- guaranteed by our
industry-leading SLA.
