Is Internet via Balloons just blue sky thinking?

Recently there has been some speculation that Google is looking into expanding the Internet into rural Africa using balloons.

HAPS are deployed above the range of commercial flights but lower than satellites – allowing for lower latency times and less energy consumption.

Since HAPS would need to be tethered to the ground, thus causing a major hazard for commercial airliners,  I think this is a blue skies idea floated early for PR purposes, or wild speculation on the part of tech journalists.

Getting connectivity to rural areas is going to happen when it becomes commercially and practically possible, as the mobile phone companies have been demonstrating through their actions over the last 15 years building out networks some really challenging locations.  I really don’t believe it will be driven by technical innovation.

Regarding the West African cable – the SAT3 cable has been operational since 2001, landing in several West African countries.  Local circumstances ranging from absence of local network links to corruption and civil war, have limited the usage of this in most cases, meaning the local ISPs and us still use expensive VSAT links to connect to the internet even in countries like Nigeria.  We’re able to get cheap great internet connections in South Africa, Mozambique and surprisingly Zimbabwe via this cable!  It’s the problems that lead to NGOs like us working in those countries that keep our internet connection costs high not a lack of technology.

When I look at the problems we face at Christian Aid right now in connectivity, they really stem from two things.  High bandwidth requirements, and a failure to budget adequately for the real costs of supplying that amount of bandwidth in some locations where we work.   We aren’t able to take an active role in cutting our costs unless we are taking measures to reduce our requirements!

Thinking back to books about rural connectivity from only 10 or 15 years ago NGOs were proud about sending and receiving email over HF radio links!  Our expectations have risen since then, but are we really getting the value from bandwidth hungry tools proportionally to the extra costs we have to spend to use them in remote locations.

 

Can you work with the Chaos Monkey?

At the Nethope Conference, one of the better plenary sessions was by Joe Baguley of VMware.  One of the things he mentioned in his talk that resonated for me was something that Netflix had developed called the Chaos Monkey.

The Chaos Monkey is a programme that Netflix run on their systems that randomly shuts down processes and services.  The idea is that the world is a chaotic place, and at some point one of your processes or services will shut down.  The chaos monkey simulates this, forcing everyone to design systems that can handle this or that part failing.

This seems to be a particularly important concept to grasp, particularly when building on platforms that market themselves as extremely resiliant.

At Christian Aid, I don’t think we need to build our own chaos monkeys. In our international environment, we are frequently interrupted by chaotic events, from giant signs falling on VSAT dishes (Abuja, 2008) to seemingly random VPN outages caused by ISP config errors (Port Au Prince, Dhaka, Delhi, La Paz, all to often recently).  Whilst these are a proper pain in the derrier, we must learn from them, and take this learning to build more resilant infrastructure, but also organisational processes that can handle everything from Earthquakes to SAN failure taking out our email system

The Chaos Monkey teaches us to expect the unexpected.
