Foreign Hackers Attack Canadian Government

An unprecedented cyberattack on the Canadian government also targeted Defence Research and Development Canada, making it the third key department compromised by hackers, CBC News has learned. ... While there is no definitive proof, of course, that China was behind these attacks, there is a lot of circumstantial evidence that points in that direction. China (allegedly) has a long history of engaging in espionage activities in order to gain access to information. In the United States, this is sometimes referred to as cyber warfare, but I think that cyber espionage is a better choice of terms. more

IPv6 in China

Much has been written about the progress of the adoption of IPv6 over the years. I know I've been guilty of adding my writings into the pool, and this article is a further contribution to that pool of observations and measurements. In this case, I want to look in some detail at the deployment of IPv6 in China. Why is China so important in this story of IPv6 deployment? more

IPv6 or IPv4? What Will We See in the First Wave of LTE Networks?

All the talk early this year seems to be about LTE deployment to alleviate chronic Apple and other smartphones induced indigestion on the AT&T and other major Mobile Networks swamped by data traffic. The telluric shift albeit the user will not care or should not notice is that when he or she will power on that smartphone or whatever the communicating Swiss Knife will be called, it will request an IP address to complete an IP based call. more

Zero Rating, a Poisoned Chalice for the Developing World

A very Interesting meeting The Internet Governance Forum (IGF) with an ambitious theme of connecting the worlds next billion people to the Internet took place in early November 2015 in a beautiful resort city of João Pessoa in Brazil under the auspice of the United Nations. Few citizens of the world paid attention to it yet the repercussions of the policy issues discussed affect us all. more

The 5G Race in Reno

The past week in the 5G world was notable because of some major events in Reno in the 5G race to roll out the full 5G specifications known as Release 16. A set of seven major concurrent industry standards meetings were hosted there over five days last week. The metrics are indicative of who really participates in and shapes the rapidly emerging 5G platforms. more

Did Google’s Infrastructure Coup Work?

There is no doubt that the Google fibre rollout in Kansas City has been a success. Take-up rates are as high as 75%. However, when it was first announced in 2010, we stated that the real reason behind Google's entry into this market was to prove that FttH can be cost-effective and can generate a profitable return -- in the hope that the sluggish telcos would become more active in the rollout of FttH networks. Yet, Google is proving that this indeed can be done, the telcos remain sluggish in deploying FttH. more

Another Day, Another Set of Hacking Attacks. News At 11.

While reading Reuters I came across a news article indicating that a number of high profile agencies - from the United Nations to the Canadian Government to government of Taiwan - were broken into over a period of the past five years. ... I'll say it right now, even though I haven't been briefed on it. It was China. more

The Causes of Network Outages: Underlying Causes, Growing Threats and Industry Implications

The Uptime Institute (UI) is an IT industry research firm best known for certifying that data centers meet industry standards. UI issues an annual report that analyzes the cause of data center outages. The causes for data center outages are relevant to the broadband industry because the same kinds of issues shut down switching hubs and Network Operations Centers. more

Google Ends Domain-Fronting Feature Used by Censorship Tools

A recent change in Google's network architecture has put a stop to a so-called "domain-fronting" feature that allowed services use Google's network to get around state-level internet blocks. more

Let American Telcos and Cablecos Merge - But Declare Infrastructure a Utility

While there is much discussion in the United States about the mergers of Comcast and Time Warner Cable, and of AT&T and DirectTV, issues such as this are generally discussed from a very narrow perspective and, we maintain, from the wrong underlying telecoms regime operating in that country - one that has stifled competition in the telecoms for nearly two decades. The same wrong parameters apply to the endless debates on net neutrality an issue that is, by the way, largely of significance to the US market alone. more

A DNS View of Lockdown

At NANOG 79 earlier this month Craig Labowitz from Nokia Deepfield presented on the impact on the COVID-19 pandemic on Internet use. The approach to the analysis used real-time streaming telemetry from Communication Service Provider (CSP) backbone and aggregation routers, and the data analysis covered content provider networks in North America, Europe and parts of Asia. more

Why We’ll Never Replace SMTP

An acquaintance asked whether there's been any progress in the oft-rumored project to come up with a more secure replacement for SMTP. Answer: No. Truly, spam isn't a technical problem, it's a social one. If we could figure out some way to make mail recipient networks and hosts willing to shun known bad actors, even at the cost of losing some real mail for a while until the bad actors cave, it would make vastly more difference than any possible technical changes. more

Another Year of the Transition to IPv6

I bet that nobody believed in 1992 that thirty years later, we'd still be discussing the state of the transition to IPv6! In 1992 we were discussing what to do about the forthcoming address crunch in IPv4, and having come to terms with the inevitable prospect that the silicon industry was going to outpace the capacity of the IPv4 address pool in a couple of years, we needed to do something quickly more
