Cuba's (Hopefully Limited) ADSL Expansion

In 2015, ETECSA announced/leaked a plan to make ADSL service available in 50% of Cuban homes by 2020. I was skeptical. Doing so would mean investing a lot of money for obsolete technology between 2015 and 2020. They have recently announced the availability of ADSL connectivity at homes in portions of seven cities and, by December, they say some home connectivity will be available in every province. more»

The Role of the BFR in SpaceX's Satellite Internet Service

SpaceX started with their Falcon 1 booster followed by several versions of the Falcon 9. The Falcon Heavy will fly later this year, and the rocket that will take the first person to Mars is called, for now, the Big F*ing Rocket or BFR. The 150-ton BFR payload will be ten times that of the Falcon 9. It will have an extra landing-guidance engine for reliable reusability and SpaceX also expects to be able to soft-land and reuse the second-stage payload rocket as well as its protective nose cone, substantially reducing cost per launch. more»

Inevitability of Global Standards for Non-Terrestrial Spectrum Sharing

Three companies, SpaceX, OneWeb and Boeing have announced ambitious plans to put thousands of Internet-service satellites in non-geostationary low-Earth orbit (NGSO) and other companies like ViaSat and SES are currently operating hundreds of communication satellites in medium-Earth and higher, geostationary orbits. With so many satellites orbiting in different planes and at different altitudes, there are bound to be frequent "inline events"... more»

What Does the Future Hold for the Internet?

This is the fundamental question that the Internet Society is posing through the report just launched today, our 2017 Global Internet Report: Paths to Our Digital Future. The report is a window into the diverse views and perspectives of a global community that cares deeply about how the Internet will evolve and impact humanity over the next 5-7 years. We couldn't know what we would find when we embarked on the journey to map what stakeholders believe could shape the future of the Internet... more»

Google Global Cache Servers Go Online in Cuba, But App Engine Blocked

Cuban requests for Google services are being routed to GCC servers in Cuba, and all Google services that are available in Cuba are being cached -- not just YouTube. That will cut latency significantly, but Cuban data rates remain painfully slow. My guess is that Cubans will notice the improved performance in interactive applications, but maybe not perceive much of a change when watching a streaming video. more»

The Madness of Broadband Speed Tests

The broadband industry has falsely sold its customers on "speed", so unsurprisingly "speed tests" have become an insane and destructive benchmark... marketing departments at ISPs refuse to define what experience that actually intends to deliver (and what is unreasonable to expect), the network engineers are left with a single and simple marketing requirement: "make it better than it was". more»

Can Constellations of Internet Routing Satellites Compete With Long-Distance Terrestrial Cables?

Three companies, SpaceX, OneWeb, and Boeing are working on constellations of low-Earth orbiting satellites to provide Internet connectivity. While all three may be thinking of competing with long, terrestrial cables, SpaceX CEO Elon Musk said "the goal will be to have the majority of long-distance traffic go over this (satellite) network" at the opening of SpaceX's Seattle office in 2015. Can he pull that off? more»

The One Reason Net Neutrality Can't Be Implemented

Suppose for a moment that you are the victim of a wicked ISP that engages in disallowed "throttling" under a "neutral" regime for Internet access. You like to access streaming media from a particular "over the top" service provider. By coincidence, the performance of your favoured application drops at the same time your ISP launches a rival content service of its own. You then complain to the regulator, who investigates... It seems like an open-and-shut case of "throttling" resulting in a disallowed "neutrality violation". Or is it? more»

Large BGP Leak by Google Disrupts Internet in Japan

At 03:22 UTC on Friday, 25 August 2017, the Internet experienced the effects of another massive BGP routing leak. This time it was Google who leaked over 160,000 prefixes to Verizon, who in turn accepted these routes and passed them on. Despite the fact that the leak took place in Chicago, Illinois, it had devastating consequences for the internet in Japan, half a world away. Two of Japan's major telecoms (KDDI and NTT's OCN) were severely affected, posting outage notices (KDDI / OCN pictured below). more»

Boeing's Satellite Internet Project

I recently posted updates on the satellite Internet service projects of SpaceX and OneWeb. OneWeb and SpaceX have received a lot of publicity, but there is a third entry in the global satellite Internet race -- Boeing. Boeing has applied for a license to launch a constellation of 2,956 Internet-access satellites orbiting at an altitude of 1,200 km. (In a subsequent amendment, the orbits were lowered to three different levels). They outlined a two phase plan... more»
