Widespread Network Outages Disrupt AT&T Services Across the US

In a significant service disruption early Thursday, AT&T's network experienced widespread outages, affecting cellular service and internet connectivity for users across the United States. According to the tracking site Downdetector, the issues began around 4 a.m. ET, with over 32,000 reports of outages, which surged to more than 71,000 by 8 a.m. ET. more

Cuba’s New WiFi Regulations – Good, Bad or Meh?

Soon after ETECSA began rolling out WiFi hotspots for Internet access, people began linking to them from homes and community street nets. These connections and importing the WiFi equipment they used were illegal, but generally tolerated as long as they remained apolitical and avoided pornography. Regulations passed last month legalized some of this activity in a bid to boost connectivity by allowing Internet access from homes and small private businesses like restaurants and vacation rentals that are located close enough to a hotspot to establish a WiFi connection. more

The Network of Probabilities

At eComm, I interviewed on stage Neil Davies, founder of Predictable Network Solutions. (Disclosure: they are a consulting client, we are working together to commercialise their technology.) The transcript of the interview is up on the eComm blog, titled The Internet is Not a Pipe and Bandwidth is Bad. Neil's achievement is a breakthrough advance in the use of applied mathematics to describe behaviours of statistically multiplexed networks. more

The Impacts of Hurricanes Harvey, Irma, and Maria on the Internet

The devastation caused by several storms during the 2017 Atlantic hurricane season has destroyed neighborhoods and taken lives across a number of Caribbean island nations including Texas and Florida in the United States. Senior Director of Internet Research & Analysis at Oracle Dyn Global Business Unit has posted a blog that takes a look at the impacts. more

Observations in and Around the UN Broadband Commission

The 7th meeting of the UN Broadband Commission in Mexico City was again a good combination of announcements about new plans, results of previously undertaken activities, and views on the future of broadband. Very noticeable was the enthusiasm and acknowledgement of the impact of ICT, and of broadband in particular. In September 2012 the Commission launched its working group on gender equality. Research undertaken by the various members of the workgroup provided somewhat similar results. more

Network Dis-Aggregation and SDN: Different, But Related

Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more

Don’t Make the Internet Safe for Monopolies

This week I'm going to Washington to argue against regulating Internet access as if it were phone service. Twenty years ago I was there for the same reason. My concern now as it was then is that such regulation will damage the economy and reduce opportunity by stifling innovation and protecting the current dominant players from the startups which would otherwise threaten them. more

Today’s Internet: More BRICS Than Westerners

Something over 55% of landline broadband users are in the "Global South," about 500M. The South is about 65% if you include "wireless-only" many of which are 4G LTE at ten megabits or more. The gap is widening rapidly and will increase by well over 70M in 2018. Six large developing countries are growing 5% or more in the last year, compared to only one in the developed world. China is adding ~30M more each year. Most developed countries are between 75% and 95% connected. That leaves little room for growth. more

Starlink in Ukraine: What Three Years of Wartime Connectivity Taught Us

What began as an emergency response evolved into critical wartime infrastructure. Ukraine's experience with Starlink reveals the strategic risks and benefits of relying on privately operated networks for national resilience and defence. more

Traffic Management: An Undefined Term

In Europe yet another package is discussed, and it includes issues related to what I guess one could call Network Neutrality. And, as usual, at the end of the game, texts are negotiated that does not have much meaning in reality. Negotiations on what words imply, while I as an engineer have absolutely no idea what either of the parties actually mean... more

Is the Passion Over Net Neutrality Misguided? A New Paper Offers a Fresh Technical Approach

"Net neutrality" is implicitly framed as a debate over how to deliver an equitable ration of quality to each broadband user and application. This is the wrong debate to have, since it is both technically impossible and economically unfair. We should instead be discussing how to create a transparent market for quality that is both achievable and fair. In this paper I propose an alternative approach that (potentially) meets the needs of both consumer advocates and free market proponents. more

BT and Ofcom

About 16 months ago, I heard Ed Richards of Ofcom speak at a CITI conference at Columbia, and blogged about it here. I remember thinking that Richards didn't seem to think that highspeed access to the internet was all that important. The market had to demand it, and the market wasn't being demanding. Also, he wasn't interested in government intervention to support highspeed access... more

It’s Official: Value Moving to Edge

It's official. A team of market analysts from Oppenheimer are saying [PDF] what I've been saying since 1997, that the apps are separating from the network, and this is driving a wave of "explosive innovation." more

A Look Inside the European Response to Spam

Last week the European Network and Information Security Agency (ENISA), which assists the European Commission and its member states with network and information security issues, published its third Anti-Spam Measures Survey. The survey provides insight into how network operators in Europe are responding to the continued onslaught of email spam. more

47 of the World’s 70 Largest Economies Now Have Active 5G Networks, US Takes the Lead Over China

The United States has taken the lead in the number of 5G cities, surpassing China for the first time. There has been a large increase of 5G cities in the U.S., with 503 cities now having 5G networks, compared to 297 in May 2022. more
