Doug Madory is the director of internet analysis for Kentik where he works on internet infrastructure analysis. The Washington Post dubbed him “The Man who can see the Internet” for his reputation in identifying significant developments in the global layout of the internet. Doug is regularly quoted by major news outlets about developments ranging from national blackouts to BGP hijacks to the activation of submarine cables. Prior to Kentik, he was the lead analyst for Oracle’s internet intelligence team (formerly Dyn Research and Renesys).
This fall Amazon Prime Video became the exclusive broadcaster of the NFL’s Thursday Night Football. This move continued Prime Video’s push into the lucrative world of live sports broadcasting. As you can imagine, these games have led to a surge in traffic for this OTT service.
On August 17, 2022, an attacker was able to steal $235,000 in cryptocurrency by employing a BGP hijack against Celer Bridge, a cryptocurrency service. While this incident is the latest such attack, there are lessons beyond the world of cryptocurrency for any organization that conducts business on the internet.
Our analysis from earlier this year estimated that the majority of internet traffic now goes to routes covered by ROAs and is thus eligible for the protection that RPKI ROV offers. This analysis takes the next step in understanding RPKI ROV deployment by measuring the rejection of invalid routes.
Since the beginning of June 2022, internet connectivity in the Russian-held Ukrainian city of Kherson has been rerouted through Crimea, the peninsula in southern Ukraine that has been occupied by Russia since March 2014. As I explain in this blog post, the rerouting of internet service in Kherson appears to parallel what took place following the Russian annexation of Crimea.
On July 8, 2022, Canadian telecommunications giant Rogers Communications suffered a catastrophic outage taking down nearly all services for its 11 million customers in the largest internet outage in Canadian history. We dig into the outage and debunk the notion that it was caused by the withdrawal of BGP routes.
On Tuesday, June 7, internet users in numerous countries from East Africa to the Middle East to South Asia experienced an hours-long degradation in service due to an outage at one of the internet’s most critical chokepoints: Egypt. In this blog post, we review some of the impacts as well as compare how this disruption affected connectivity within the three major public cloud providers.
Last night, Kansas topped the University of North Carolina in a thrilling come-from-behind victory to win their fourth championship in men’s college basketball. It was also notable in how viewers saw the game. Instead of being aired on network television like in the past, the game was carried on TBS requiring viewers to have either a cable TV package or use a streaming service to watch the game. Here’s what we saw.
In our updated blog post, read why international telcos Cogent and Lumen say they are taking action against Russia.
Just in time for Valentine’s Day, we’re announcing our newest labor of love: Kentik Market Intelligence (KMI), a new product that spells out the internet ecosystem.
On Saturday, the pacific island nation of Tonga was decimated by a massive volcanic eruption that was visible from space. At 5:27pm local time, the underwater volcano Hunga Tonga-Hunga Ha’apai unexpectedly erupted, sending ash and debris for hundreds of miles. As of this writing, all internet and telephone communications between Tonga and the rest of the world are still down.
Last month, the long-awaited film adaptation of Frank Herbert’s sci-fi epic Dune was released in theaters and on HBO Max. Directed by Canadian filmmaker Denis Villeneuve, the movie was a hit at the box office as well as via streaming, leading to another OTT traffic surge.
Last Tuesday, September 14th was the second Tuesday of the month, and for anyone running a network or working in IT, you know what that means: another Microsoft Patch Tuesday. Doug Madory looks at how the resulting traffic surge can be analyzed using Kentik’s OTT Service Tracking.
There has been a new development in The Mystery of AS8003.
As you may recall, this was the AS number registered to a defunct company in Florida that appeared earlier this year in the global routing table announcing over 175 million IPv4 addresses belonging to the US Department of Defense.
Well, that just changed.
Africa’s regional internet registry, AFRINIC, is involved in a legal dispute over an increasingly valuable commodity: IPv4 address space. Kentik’s Doug Madory takes a deeper look at what’s happening.
On January 20, 2021, a great mystery appeared in the internet’s global routing table. An entity that hadn’t been heard from in over a decade began announcing large swaths of formerly unused IPv4 address space belonging to the U.S. Department of Defense. Registered as GRS-DoD, AS8003 began announcing 18.104.22.168/8 among other large DoD IPv4 ranges.
In the past 24hrs, Myanmar experienced a military coup d’état during which prominent government figures like Nobel laureate Aung San Suu Kyi were detained and internet service was almost entirely blacked out.
Here is what the shutdown looked like in our data (with annotations for timing) for Myanmar’s big four: Myanma Posts and Telecommunications (MPT), Telenor Myanmar, Ooredoo Myanmar, and Mytel.
Last week I had the honor to participate in the PTC 2021 conference. Held in Hawaii every January, PTC’s annual conference is the Pacific Rim’s premier telecommunications event. Although this year’s conference was all virtual (no boondoggles to Honolulu!), it was no less important as the theme this year was New Realities. In the following blog post, I summarize what I presented in my PTC panel entitled Strategies to Meet Network Needs.
The shutdown in Egypt not only shifted the dynamics of protest in the 21st century, it was a watershed moment for the internet community — from technical organizations like Renesys to digital rights advocacy groups like Access Now. The era of the large-scale government-directed internet shutdown had truly begun.
