A Look Back at the Pandemic and What Was Missed in the ISPs’ Broadband Performance Reports

I was looking back at industry reporting a year ago after the impact of the pandemic first hit our broadband networks. Almost every big ISP issued press releases talking about how well it had weathered the pandemic and bragged about the resiliency of its networks. It turns out that these ISP press releases largely missed the point. They are right that their networks didn't crash, but once we understood the nature of the changes in broadband traffic due to the pandemic, that wasn't a big surprise. more

Rumblings for an In-Session Recommendation Engine at Email Service Providers (Part I)

Email Campaign builders (marketers) are flying blind. I know ESPs are genuinely timely about rolling out new products for their marketers, but there is a colossal gap in adopting data science and MLops into the email campaign building workflow.  Even MailChimp does not seem to have the answer just yet, and half-baked attempts over the years to optimize the subject line haven't been inspiring. more

Transport vs. Network

One of the basic tools in network design is the so-called "stacked" protocol model. This model was developed in the late 1970s as part of a broader effort to develop general standards and methods of networking. In 1983, the efforts of the CCITT and ISO were merged to form The Basic Reference Model for Open Systems Interconnection, usually referred to as the Open Systems Interconnection Reference Model or the "OSI model." more

NSA Takes a Leadership Seat at the Global 5G Security Table

It has been a long time coming. In the world of global 5G security, there is only one principal forum. The somewhat cryptically named 3GPP SA3 is dedicated to 5G security and holding its 103rd meeting electronically next week from 17 to 28 May with 772 submitted documents and 189 participants registered. SA3 meets every 60 days and exists at the security center of an ecosystem of numerous technical groups encompassing many hundreds of companies, industry organizations, and government agencies worldwide. more

To 5.5G and Beyond

I recently saw an article in FierceWireless that reports that Huawei thinks we are going to need an intermediate step between 5G and 6G, something like 5.5G. To me, this raises the more immediate question about why we are not talking about the steps between 4G and 5G? The wireless industry used to tell the truth about cellular technology. You don't need to take my word for it... more

Mistrust of ICANN Is Fully Vindicated

Recently, I have been reporting on a highly questionable auction scheme for a single domain name, o.com, which is currently being improperly warehoused by ICANN along with a number of other .com and .net domain names. This violates ICANN's Bylaws -- but, so what? more

Still Waiting for IPv6

It's now been a decade since the world officially ran out of blocks of IP addresses. In early 2011 the Internet Assigned Numbers Authority (IANA) announced that it had allocated the last block of IPv4 addresses and warned ISPs to start using the new IPv6 addresses. But here we are a decade later and not one of my clients has converted to IPv6. more

Ten Years of Passive DNS

The report, "A Decade of Passive DNS" provides a longitudinal analysis of the use and popularity of top-level domains over a ten-year period. The findings are based on what Farsight Security has seen in passive DNS from 2010-2019 based on a ten-year data rollup, excluding DNSSEC-related records. This study allows us to report on four measures for that period for each of the 1,576 IANA-recognized TLDs. more

The Slow Death of Satellite TV?

There have been rumors for years about merging Dish Networks and Direct TV to try to gain as much market synergy as possible for the two sinking businesses. It's hard to label these companies as failures just yet because between two companies collectively still had 21.8 million customers at the end of 2020 (DirectTV 13.0 million, Dish 8.8 million). This makes the two companies collectively the largest cable TV providers, with Comcast at 19.8 million and Charter at 16.2 million. more

Huawei’s Q1 2021 Phone Sales Down by Over 30%

"2021 will be another challenging year for us, but it's also the year that our future development strategy will begin to take shape," said Eric Xu, Huawei's Rotating Chairman. Huawei generated CNY152.2 billion in revenue, a 16.5% decrease year-on-year. The Network Business continued to grow. It wasn't officially announced1, but consumer products other than phones probably increased sales. The fitness tracker, earbuds, and watches are winning strong reviews. more

The $100 Billion National Broadband Plan for America

The new Biden Administration in the USA laid out a $100 billion proposal for broadband investment as part of its $2 trillion+ infrastructure plan. Under the proposal, the plan is to provide national broadband coverage. The Administration will use better competition measures, such as price transparency, the use of public utility infrastructure, and subsidies for low-income households to achieve its goals. more

Leaked Documents Reveal Xi Jinping’s Communist Chinese Plan to Control the Internet’s Root

Yesterday, The Epoch Times reported on leaked internal Chinese government documents revealing that premier Xi Jinping has "personally directed the communist regime to focus its efforts to control the global Internet, displacing the influential role of the United States." Xi's ultimate aim is for the Chinese Communist Party (CCP) to wield "discourse power" over communications and discussions on the global geopolitical stage by controlling content on the Internet. more

Think Beyond .com: From Country Codes to Internationalized Domain Names

One of the major takeaways from the Web Globalization Report Card is the importance of providing "front doors" to your localized websites. These doors begin with the addresses themselves, which may not include the .com domain. In fact, I'd recommend that most localized websites not use the .com domain, as this is an overloaded domain. This article looks at the many ways brands are creating more localized addresses, beginning with country code top-level domains (ccTLDs). more

Avoiding Low-Earth Orbit Collisions – the Clock Is Ticking

There was a recent dispute between OneWeb and SpaceX regarding the possibility of a collision between two of their low-Earth orbit (LEO) satellites. OneWeb's satellite (OneWeb-1078) was launched on March 25 and headed for its orbit at an altitude of 1,200 km when, in early April, it passed near a SpaceX satellite (Starlink-1546) in orbit at about 450 km. There was no collision, but subsequently, OneWeb's government affairs chief Chris McLaughlin said... more

Trusted Notifiers and the Future of DNS Abuse

Efforts have been ongoing in the ICANN community to develop a better understanding of its role in the combat of abuse. This theme has been rising in prominence every year since 2018, and 2021 appears to be the tipping point, in which consensus has built around the idea that more can be accomplished in terms of reducing the impact of rogue actors using the Internet for malicious purposes. more
