Bangladesh Connects via India

The Internet of Bangladesh has been connected to the world by a single submarine cable, Sea-Me-We 4 (SMW4), since this 18,800 kilometer-long optical-fiber system made its landing at Cox’s Bazar in 2006. However, in the nearly seven years since SMW4′s activation, national Internet outages have plagued Bangladesh with some regularity. When their portion of this system is sabotaged, suffers a failure or is down for maintenance, virtually all Internet bandwidth for the 7th most populous country in the world disappears, forcing local providers to fall back to slow and expensive satellite services or to simply wait for restoration.However, recent national outages due to planned SMW4 maintenance have revealed that some Bangladeshi providers have now activated a long-awaited second connection to the Internet via a terrestrial link to India. We’ll examine this new development here and highlight those providers who can now offer fault-tolerant Internet service for the first time in Bangladesh. India-Bangladesh.jpg

Cuban Fiber: Completo?

For more latest information, please follow us on Twitter: @Renesys

Cuban Internet connectivity continues to evolve by the hour, with a new, faster mode of operation in evidence as of this morning. Our measurements from around the world suggest that Cuban technicians may have completed the work they began a week ago, creating the first bidirectional Internet paths that are free of satellite connectivity.

Mystery Cable Activated in Cuba

Recent developments captured in a new blog here. (January 22, 2013)

In February 2011, the first submarine cable connecting the island nation of Cuba to the global internet (by way of Venezuela) landed on Siboney beach, Santiago de Cuba. In the two years since, the fate of the cable has been a mystery for Cuba observers. In the past week, our global monitoring system has picked up indications that this cable has finally been activated, although in a rather curious way, as we explain below. alba_cable.png

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.
