Why Far-Flung Parts of the Internet Broke Today

VolumeDrive is a Pennsylvania-based hosting company that uses Cogent and (since late May of this year) Atrato for Internet transit. A routing leak this morning by VolumeDrive was passed on to the global Internet by Atrato causing disruptions to traffic in places as far-flung from the USA as Pakistan and Bulgaria. Background The way Internet […]

Sprint, Windstream: Latest ISPs to hijack foreign networks

Last year my colleague Jim Cowie broke a story about routing hijacks that resulted in Internet traffic being redirected through Iceland and Belarus. Unfortunately, little has changed since then and the phenomenon of BGP route hijacking continues unabated and on an almost daily basis. In the past three days, the situation has gone from bad […]

Renesys, Dyn Join Forces

Today, we’re announcing the acquisition of Renesys by Dyn, the leading provider of Internet Performance solutions. Dyn and Renesys represent the perfect combination of Internet Intelligence assets from Renesys and Traffic Management and Message Management solutions from Dyn. We’re excited to become part of the Dyn team! Those who know both companies may ask, “What […]

Indonesia Hijacks the World

Yesterday, Indosat, one of Indonesia’s largest telecommunications providers, leaked large portions of the global routing table multiple times over a two-hour period. This means that, in effect, Indosat claimed that it “owned” many of the world’s networks. Once someone makes such an assertion, typically via an honest mistake in their routing policy, the only question […]

Turkish Internet Censorship Takes a New Turn

Internet censorship in Turkey took a new and ominous turn yesterday. In order to better seal off access to social media sites like YouTube and Twitter, the incumbent TurkTelecom began hijacking the IP address space of public DNS resolvers like those of Google. This allows TurkTelecom servers to masquerade as Google DNS servers, returning whatever […]

Serving the Global Consumer: Learning from WhatsApp

The $19B WhatsApp acquisition brings Facebook what they desperately need: 250M daily users in high-growth international mobile markets, many of them in the key under-20 demographic. But how do you design a service delivery infrastructure that can reliably reach the far corners of the earth to keep all these mobile eyeballs connected to each other? […]

A Baker’s Dozen, 2013 Edition

It has become an annual tradition at Renesys to provide a year-end review of how the Internet providers at the top of our Market Intelligence global rankings fared over the previous year. The rapid and continuous evolution of the Internet’s structure and performance remains a huge blind spot for most enterprises, even those critically dependent […]

A Baker’s Dozen, 2012 Edition

It is an annual tradition at Renesys to provide a year-end review of how the Internet providers at the top of our Market Intelligence global AS rankings fared over the previous year. The Internet remains a huge blind spot for many organizations that are buying Internet access. Market Intelligence provides the insight into who the leaders in the Internet transit marketplace are today and how they have changed over time. Back in 2008, we chose to look at the 13 providers that spent at least some time in the Top Ten that year,hence the name “Baker’s Dozen“. We looked at the top players again in 20092010 and 2011. A lot has changed over the years and for 2012, we welcome two new members to this exclusive club,PCCW and XO. As predicted last year, we also say good-bye to a declining AT&T and Savvis. While AT&T’s departure from the top of the global stage may be surprising to some, Savvis really hasn’t left as it is now part of CenturyLink, which also owns Qwest. And while Qwest did leave our top global rankings in 2011, they have now returned as part of a reinvigorated CenturyLink.

As you read this blog, keep in mind that all of the rankings we discuss are relative to IPv4, the Internet protocol carrying over 99% of all Internet traffic. (For example, compare total traffic to IPv6 traffic at the very busy Amsterdam Internet Exchange.) While we did also review IPv6 rankings last year, so little has changed that we’ll just refer you to that blog or, for more current information, our Market Intelligence product offering which covers both IPv4 and IPv6 in detail. So let’s dive in and highlight a few of the trends and changes we observed in 2012.

A Baker’s Dozen, 2011 Edition

It’s become an annual tradition at Renesys to provide a year-end review of how the Internet providers at the top of our Market Intelligence global AS rankings fared over the previous year. Back in 2008, we chose to look at the 13 providers that spent time in the Top Ten in our IPv4 rankings, hence the name “Baker’s Dozen“. We looked at the same group in 2009 and 2010. This year, we welcome a new member to the group, Telecom Italia Sparkle, or simply Sparkle, and say good-bye to Qwest. We report on a resurgent Cogent and a declining AT&T and Savvis. These latter carriers will probably disappear entirely from next year’s edition to be replaced with the likes of PCCW or perhaps Hurricane Electric. Finally, in this edition, we’ll take our first glimpse at global IPv6 rankings. Complete ranking information about the IPv6 Internet is now part of our Market Intelligence product offering. So let’s dive into the data and highlight some trends and changes we observed in 2011.

Satellite Service Sets in Lebanon

Early last month, my blog “Pinning Down Latency” included this prediction:

In the coming weeks we expect to see a dramatic shift in transit as Lebanese providers move away from expensive and high-latency satellite service to IMEWE-based service.

Well, it didn’t take long for this to play out.
