Our Favorite Blogs from 2017

2017 was certainly a memorable year for Oracle Dyn. As we enjoy the winter break, we decided to look back at some of our favorite and most popular blog posts from 2017. In the spirit of The 12 Days of Christmas, we’re sharing our 12 best blogs. Spoiler alert: there are no lords a leaping.

Re-reading these posts it is amazing how much happened in only 365 days and the breadth of topics we covered. We hope you enjoy re-discovering these classic posts as much as we did.

Subsea cables

Doug Madory, from the Internet Intelligence team, started 2017 off by sharing recent subsea cable developments. As abstract as a concept like “the internet” can be, it is important to remember that at its core it still relates back to the physical. With governments discussing how best to protect undersea cables, this is a topic not going away in the next year.

Oracle + Dyn

For many of us at Dyn, 2017 will always be remembered as the year we became part of Oracle. In this post, Kyle York, GM and VP, Business & Product Strategy, shares the benefits both companies bring to each other. As the year has progressed, we’ve seen Kyle’s words become reality. We’ve officially launched DNS and Email products as part of Oracle Cloud Infrastructure and there is plenty of more exciting work ahead in 2018.

Baker’s Dozen

Earl Zmijewski’s yearly ranking of Internet providers is always a must read for anyone interested in internet routing and transit. With General Data Protection Regulation (GDPR) on the horizon in 2018, understanding who your providers are and where exactly your data travels will be top of mind for all European businesses.


Companies are often like living, breathing organisms that have their own lifecycle. In this piece, long-time Dyn employee Matt Toy shares why he decided to return to the company. It is a great lesson on culture that every company, regardless of size, could benefit from reading.

Living on the edge

Kyle’s post above discussed the benefits Dyn brought to Oracle. In this post, Trip Kucera, director of marketing communications, writes about the cloud edge, a place where much of the innovation is happening within cloud. With its long history as a pioneer in traffic management and load balancing, Oracle Dyn is uniquely positioned to be a leader in the cloud edge.

What is a hostname?

At Oracle Dyn we want to be a source of information that people use to better understand the internet. We often write technical how-to articles on using our products but we also want to supply straight forward and understandable explanation of key terms and concepts. In her article, “What is a hostname?”, Christine Graham, Software Development Manager, walks through every question you may have had but never asked about hostnames. It is a good introduction or reminder, depending on your knowledge level.

Controlling the internet

In Doug Madory’s earlier blog, we reminded readers that the internet is really a bunch of cables. In this classic post, Chris Baker takes a peek behind the curtain and discusses the million dollar question: who actually controls the internet?


Since we’re looking back at 2017, it only makes sense to share a post on Reverse DNS (see what we did there). Katie Smith, Oracle Dyn Technical Account Manager, discusses what Reverse DNS, how it works, and why it’s important to a business.


In August, Doug Madory reported on a large BGP leak that happened in Chicago but had a disruptive impact on the internet in Japan. This is a great example of the interconnectedness of the internet and also its volatility. Doug concludes his piece by reminding us that the internet is a team effort and we must work together to help ensure its performance.


In another example of the volatility of the internet, David Belson, senior director of internet research and analysis, discusses the impact of Hurricanes Harvey, Irma, and Maria on the internet in those geographical regions. While something like the internet seems trivial, compared to the loss of life and property damage caused by those storms, the internet has become a major tool for communication and organizing relief efforts and so people’s ability to connect to it in times of emergency is important.

North Korea

In October, Doug Madory was one of the first people in the world to notice a new internet path out of North Korea. This new path came from Russia, while the previous path was from China. Having multiple internet paths increases redundancy. It also gives North Korea more options, making them less dependent on China.

Internet disruption

Redundancy is so important because it can help prevent a country from experiencing an internet disruptions. Some countries are in better situations than others. In this post, David Belson updates an all-time classic post by Jim Cowie, on the risk of internet disruption that each country has. If you’re reading this post in Africa, you may be very interested in this piece.
