BGP best path selection
The complexity and the efficiency of BGP reside in the concept of route “attributes” and the way the protocol juggles them to determine the best path. This is a quick guide (refresh of an old article), still very actual for those dealing with BGP design. I hope the following Cisco BGP best path selection diagram will be of […]

Last Month in Internet Intelligence: October 2018
The level of significant Internet disruptions observed through the Oracle Internet Intelligence Map was lower in October, though the underlying reasons for these disruptions remained generally consistent compared to prior months. For enterprises, the importance of redundant Internet connectivity and regularly exercised failover plans is clear. Unfortunately, for state-imposed Internet outages, such planning and best practices may need to include failsafes for operations while periodically offline.
Directed disconnection
On October 10, Ethiopian Prime Minister Abiy Ahmed met with several hundred soldiers who had marched on his office to demand increased pay. The Ethiopian Broadcasting Corporation (formerly known as ETV) did not cover the soldiers marching but noted that Internet connectivity within the country had been shut off for several hours to prevent “fake news” from circulating on social media. This aligned with residents’ reports of a three-hour Internet outage. The figure below shows that the disruption began around 12:00 GMT, significantly impacting both traceroutes to, and DNS query traffic from, Ethiopia for several hours.
The impact of the Internet shutdown is also clearly evident in the figure below, which shows traceroutes into Ethio Telecom, the state-owned telecommunications service provider. Similar to the country-level graph shown above, the number of Continue reading

Making the Case for Community Networks at Africa IGF
Who supplies your Internet? If you live in urban Africa, you probably get Internet access through your mobile phone or through fibre at the office or home. When you travel to rural or underserved areas, there is probably limited or no Internet because mobile network operators and Internet Service Providers (ISPs) have yet to reach these areas. But what if people in rural and underserved areas could build their own networks to provide the telecommunications services that they need?
This notion has been tried successfully in several African countries. In Kenya, Tunapanda Institute has built TunapandaNET a wireless network connecting schools and youth centres in Kibera, Kenya’s largest slum. Bosco is a solar-powered wireless network that connects community ICT centres in Gulu, Northern Uganda. PamojaNet operates a wireless network to the community in Idjwi Island on lake Kivu, Eastern DRC, close to the border with Rwanda. Others such as Machaworks in rural Zambia and Zenzeleni Networks in Eastern Cape of South Africa provide similar services. These networks have been built by local communities to provide access to both offline content and Internet access where possible to the communities that they serve.
During a session at the 2018 Africa Internet Governance Continue reading
