Top 5 Worldwide

Our network is consistently ranked among the top five networks worldwide. We own and operate one of the world's largest global tier-1 IP backbones, fully upgraded to run dual stack IPv4 and IPv6. Our backbone offers the best possible environment for content, video and data transport.

Top 5 Worldwide

Dual Stack IPv4 and IPv6

We’ve been directly involved with the development and deployment of IPv6 technology since the early 1990’s. Our IPv6 technology was the first of its kind available in the U.S. and the first globally. We operate the world’s first commercial-grade global tier 1 IPv6 backbone, spanning North and South America, Asia, Europe and Oceania. True global connectivity.

AS 2914

Of the 20,000 or so Autonomous System Numbers (ASN) in use, we have one, where other ISPs have many. That means that North and South America, Europe, Asia and Oceania all connect across a single backbone. We fully control the collection of routers that make up our ASN. We have access to extensive private peering with all other tier-1 providers and we exchange traffic, settlement-free. This means you experience stellar performance, no matter where you are because our connectivity is faster and more direct.

Fewer Hops

For some ISPs, data has to travel across multiple ASNs to arrive at its destination, which can mean up to 20 hops. With strategically located exchange points around the world, you can get to any access point on our global network in fewer hops. That means your data travels smoothly around the world with fewer delays.


We are a global tier-1 carrier, and because peering relationships are a key component of our global strategy, we have private peering with all other tier-1 providers. We’re committed to private peering and we continue to aggressively deploy capacity around the world as demand increases. We have access to all points on the Internet without paying for transit from another network. And we exchange traffic with our partners, free of charge.

We offer fast, uninterrupted Internet connections around the globe. The engineers at our Network Operations Center (NOC) provide exceptional customer support and maintenance 24 x 7 x 365. No call centers. No messages taken. You're assured the quality routing of your data and the support of our engineers.

We offer some of the most aggressive Service Level Agreements (SLAs) in the industry. Our SLAs guarantee 100% uptime, low jitter and low latency, so you get excellent service both inside and outside your country. Our backbone is managed by a single policy end to end. It's the best choice for building and expanding your IP network worldwide.
