New Research from CSC on the Impact of COVID-19 on Internet Security and Safety

Hackers are using company domain names for malicious attacks more than ever before. Established research shows that phishing and related malware attacks most commonly occur from a compromised or hijacked legitimate domain name, a maliciously registered, confusingly similar domain name, or via email header spoofing. Domain security intelligence is the first line of defense in preventing domain cyberattacks. more

Top Broadband Stories of 2021

Every year I write a blog talking about the trends that I think we're likely to see in the coming year. But 2021 was such an unusual year for all of us that I thought it would also be useful to talk about what we accomplished in the industry over the last year while fending off a pandemic. All in all, it was quite a year. more

The Year 2038 Computer Problem – a Repeat of Y2K?

The Year 2038 Problem relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer. Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038. At that time, systems might crash and be unable to restart when the time is changed to that date. It is like the Y2K problem caused by the widespread use of two decimal digits to store the year. While that problem was overhyped... more

Observations on Resolver Behavior During DNS Outages

When an outage affects a component of the internet infrastructure, there can often be downstream ripple effects affecting other components or services, either directly or indirectly. We would like to share our observations of this impact in the case of two recent such outages, measured at various levels of the DNS hierarchy, and discuss the resultant increase in query volume due to the behavior of recursive resolvers. more

When Will We See Real 5G?

The non-stop wireless industry claims that we've moved from 4G to 5G finally slowed to the point that I stopped paying attention to it during the last year. There is an interesting article in PC Magazine that explains why 5G has dropped off the front burner. The article cites interviews with Art Pouttu of Finland's University of Oulu about the current state and the future of 5G. That university has been at the forefront of the development of 5G technology and is already looking at 6G technology. more

The US-China Technology Cold War Battle Over Optical Communication in Space

The United States and its allies are in a technology cold war with China and its allies. This is evidenced by major battles like the US ban on Huawei and China's drive for technological independence and their global infrastructure program to create a digital silk road. (The cold war began under Trump, but President Biden is continuing it). There are other, less well-known battles like the battle over optical communication in space. more

Australian Farms Get Connected to the Starlink Satellites

Last year, I reported on the possibility that LEO (Low Earth Orbit) satellite-based systems might be a gamechanger for the delivery of high-speed data services, including internet access, to people in regional and remote Australia. What has become clear with the rollout of the NBN is that the quality of data connections in metropolitan cities in many cases has improved, but that the rest of Australia doesn't have a similar experience. more

2021 Domain Name Year In Review

Is it really 2022? Is it? Although many might view 2021 as another "lost" year due to the pandemic, filled with Zoom™ meetings, virtual conferences, working from home and restricted travel - there were a number of notable domain name stories which deserve to be highlighted. So, without further ado, here are the top 10 biggest domain name stories of 2021 - let's go! more

Fixed Cellular Broadband Performance

One of the first in-depth reviews I’ve found for T-Mobile’s fixed cellular broadband was published in the Verve. It’s not particularly flattering to T-Mobile, and this particular customer found the performance to be unreliable – fast sometimes and barely functioning at other times. But I’ve seen other T-Mobile customers raving about the speeds they are receiving. We obviously can’t draw any conclusions based upon a single review by one customer... more

The Future of Data Storage

One of the consequences of our increased use of broadband is a big increase in the amount the data that we store outside our homes and businesses. The numbers are becoming staggering. There are currently about 3.7 billion people using the Internet, and together we generate 2.5 quintillion bytes of online data every day. The trends are that by 2025 we'll be storing 160 zettabytes of data per year - a zettabyte is one trillion gigabytes. I store a lot more data online than I used to. I now store things in the cloud all day long. more

The 25/3 Mbps Broadband Connection Myth

There is no such thing as a 25/3 Mbps broadband connection, or a 100/20 Mbps broadband connection, or even a symmetrical gigabit broadband connection on fiber. For a long list of reasons, the broadband speeds that make it to customers vary widely by the day, the hour, and the minute. And yet, we've developed an entire regulatory system built around the concept that broadband connections can be neatly categorized by speed. more

Normalize inflated iOS 15 Email Open Rates with Unsupervised ML

Happy Holidays. In September 2021, Apple rolled out iOS 15. For high volume email senders, Apple Mail now essentially tracks every email sent as an "open." Seemingly if you are a campaign engineer, high volume sender or ESP, this change can radically affect 25% - 45% of your email subscriber base, across both B2B, B2C or D2C. Inside your email analytics platform, you should see the specific percentage of Apple Mail users in your database, thus a significant rate of change ( delta) regarding inflated "open rates." more

ICANN DNS Resolver Symposium – the Session Had Several Interesting Presentations That I Would Like to Comment On

ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more

My Broadband Predictions for 2022

It's that time of the year for me to get out the crystal ball and peer into 2022... I have no idea why it took a year for the administration to tee up a new Chairman and recommend a fifth FCC Commissioner. But once a new Commissioner is seated, the new FCC will tackle reinstating some version of Title II regulation, accompanied by net neutrality regulations. For yet another year, this won't come from Congress, which is the only permanent solution. more

The Christmas Goat and IPv6 (Year 12)

This year could be the fifth year in a row where the goat isn't burned down. But early in the morning of Dec 17th, it was on fire by an arsonist who got caught a few minutes later. So Stephan Lagerholm, who had visited me earlier for some IPv6 site seeing in Gävle and I were lucky to get this photo. The traffic went down by 5% from last year, and I don't have any good explanation for that. The visitors with many hits in the logs are always from the same countries where North America and Europe are dominating. more
