In light of the recent submarine cable failures, Doug Madory from Renesys has a detailed report on what has happened to some of the providers in four countries along the route of the cable: Egypt, Saudi Arabia, Pakistan and India. more
It's been an interesting couple of weeks for me, in mid-October 2023. I presented in a couple of panels at the 18th Internet Governance Forum meeting, held in Kyoto, Japan, and I also listened in to a couple of sessions in their packed agenda. The following week, I followed the presentations at NANOG 89, the meeting of the North American Network Operator's Group, and listened to a presentation by John Curran, the President and CEO of ARIN, where he gave his impressions of the current state of Internet Governance. more
As I type these words, I am perched on one of the benches in the main thoroughfare of the cavernous venue hosting Mobile World Congress (MWC). Above me is a video screen warning me of the perils of the infamous local pickpockets, so I know I'm definitely in Barcelona! In its current form, MWC has been the mainstay event of the telecoms business for a decade, and its roots go back to the late 1980s. The slogan of this year's event is "Mobile is Everything". I believe this phrase is a symptom of an industry suffering from dangerous strategic drift. Here's why. more
It was interesting to see that in New Zealand Vodafone had second thoughts and decided to come up with its own proposal of forming a consortium of network operators, rather than simply supporting the government's announcement of its FttH plans. Our analysis of this change of mind is that mobile operators increasingly need fibre networks to sustain the enormous growth in mobile broadband. Most mobile stations around the world are not connected to a fibre network. more
The Secure 5G and Beyond Act of 2020 has been submitted by the U.S. Congress to the White House for signing into law. It has been sitting there for several days now, but there are obviously more important developments demanding attention than a law compelling the Executive Branch to develop a 5G security strategy within 180 days through public and Federal agency consultations that will be implemented by the NTIA. more
Today's blog talks about a critical part of the broadband network that most people don't know about -- carrier hotels. These are locations that have been created for the specific purpose of allowing carriers to connect to each other. The need for carrier hotels became apparent in the year after the passage of the Telecommunications Act of 1996. That new law allowed local competition for telephone service. more
Declan McCullagh reporting in CNET: "Twitter last year began to abbreviate all hyperlinks using its t.co domain name -- which had the side effect of introducing a central point of failure where none existed before. That failure happened last night [Sunday Oct 7] around 11:30 p.m. PT when t.co went offline, meaning millions of Twitter users received 'non-existent domain' errors when trying to follow links." more
On Tuesday, 2020 U.S. presidential candidate John Delaney announced a plan to create a Department of Cybersecurity. more
In the past 24 months, distributed denial of service (DDoS) attacks have changed profoundly. Gone are the days when attackers worked under the radar, when machines were infected by botnet code unknowingly and attacks were disguised leaving very little to trace the exact origin. ... The other game-changer: It's easier than ever to execute attacks. The tools are so widely available that anyone with basic skills and a high-speed connection can become a "hacktivist." more
At Verisign, we believe that continuous improvements to the safety and security of the global routing system are critical for the reliability of the internet. As such, we've recently embarked on a path to implement Resource Public Key Infrastructure (RPKI) within our technology ecosystem as a step toward building a more secure routing system. In this blog, we share our ongoing journey toward RPKI adoption and the lessons we've learned as an operator of critical internet infrastructure. more
The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17th century to explain how light could be transmitted through a vacuum. more
Much of the discussion regarding mobile security revolves around the growing "pandemic" of mobile malware. It's not uncommon to see headlines reporting the discovery of large numbers of new malware samples. However, as Google recently pointed out, with quite a bit of data to support them, there's little discussion of real world impact of these discoveries. This raises a number of relevant questions. Is the average user likely to be infected? Where does this malware come from? These are questions that deserve analysis and thoughtful responses. more
The cellular companies have made an unprecedented push to get customers interested in 5G. Back in November, I recorded a college football game that enabled me to go back and count the twelve 5G commercials during the game. Advertising during sports events is relatively expensive, so these ads were not purchased at bargain-basement prices. The amount of money being spent on advertising 5G must be gigantic. more
I've been watching the progress of the low-orbit satellite providers, which are promising to bring broadband solutions across the planet. There has been some serious movement since the last time I discussed their status. On January 29, Starlink launched its latest round of low-orbit satellites, bringing the number in space to 242. Not all of these will be delivering broadband. The first half dozen satellites were test units to try out various concepts. more
In today's world with botnets, viruses and other nefarious applications that use DNS to further their harmful activities, outbound DNS security has been largely overlooked. As a part of multi-layer security architecture, a DNS Firewall should not be ignored. After serving as a consultant for multiple organizations, I have encountered many companies that allow all internal devices to send outbound DNS queries to external DNS servers - a practice that can lead to myriad problems. more
