Iran: Latest Nation to Host Critical Global Internet Infrastructure
As crippling economic sanctions are poised to be lifted by the United States, Iran is starting to emerge from its isolation as a regional and, in a very limited sense, global Internet player. Iran continues to methodically build out its Internet infrastructure, working on its domestic connectivity (including IPv6), providing service to neighboring countries (such as Iraq and Afghanistan), stockpiling limited IPv4 address space, and providing a strategic terrestrial alternative to vulnerable submarine cables.
Recently, Iran began hosting a root DNS server, thereby potentially providing this critical service to the rest of the world. In this blog, we’ll explore some of these latest developments and their challenges. In November, European Internet registrar RIPE will hold its regional operator meeting (MENOG) in Tehran, where attendees from around the world will learn firsthand about recent developments in the fast-growing Iranian Internet.
K-root Debuts in Iran
As most readers of this blog will know, when you access any resource on the Internet by name (e.g., www.cnn.com), your computer must first convert this name into an IP address (e.g., 23.235.46.73), which it then uses to gain access to Continue reading

Intellectual virtue and the engineer
On the 19th of January in 2009, Captain “Sully” Sullenberger glided an Airbus A320 into the Hudson River just after takeoff from LaGuardia airport in New York City. Both engines failed due to multiple bird strikes, so the ditching was undertaken with no power, in a highly populated area. Captain Sullenberger could have attempted to land on one of several large highways, but all of these tend to have heavy traffic patterns; he could not make it to any airport with the power he had remaining, so he ditched the plane in the river. Out of the 155 passengers on board, only one needed overnight hospitalization.
There are a number of interesting things about this story, but there is one crucial point that applies directly to life at large, and engineering in detail. Here’s a simple question that exposes the issue at hand—
Do you think the Captain had time to read the manual while the plane was gliding along in the air after losing both engines? Or do you think he just knew what to do?
Way back in the mists of time, a man named Aristotle struggled over the concept of ethics. Not only was he trying to Continue reading

Why You Should Adopt A Cloud-First Networking Strategy
The rise of hybrid cloud in the enterprise means that network engineers need to focus on enabling and supporting cloud in all its forms.Learn SDN with Virtual Routers and Switches
Bryan would love to get hands-on SDN experience and sent me this question:
I was recently playing around with Arista vEOS to learn some Arista CLI as well as how it operates with an SDN controller. I was wondering if you know of other free products that are available to help people learn.
Let’s try to do another what-is-out-there survey.

I advertised to you recently another great virtual lab environment – Unified Networking Lab – with tools like that one I practiced the cool technologies of Alcatel-Lucent Service Routing platform and prepared to many certification exams. And I encourage you to go the same way, not just read the books and force the dumps, but actually build a topologyHappy 5th Birthday, CloudFlare!
CloudFlare customers recorded videos to celebrate our first five years
Today is September 27, 2015. It's a rare Super Blood Moon. And it's also CloudFlare's birthday. CloudFlare launched 5 years ago today. It was a Monday. While Michelle, Lee, and I had high expectations, we would never have imagined what's happened since then.
In the last five years we've stopped 7 trillion cyber attacks, saved more than 94,116 years worth of time, and served 99.4 trillion requests — nearly half of those in the last 6 months. You can learn more from this timeline of the last five years.
Celebrating by doing the impossible
Every year we like to celebrate our birthday by giving something seemingly impossible back to our users. Two years ago we enabled on our Automatic IPv6 Gateway, allowing our users to support IPv6 without having to update their own servers. Last year we made Universal SSL support available to all our customers, even those on our free plan. And this year, we announced the expansion across Mainland China, building the first truly global performance and security platform.

Closing out Projects
We put a lot of energy into new projects. We argue about the design, we plan the cutover, we execute it…and then we move on. But decommissioning the old system is critical part of any project. It’s not over until you’ve switched off the old system.
Years ago I was involved in the buildout of a new network. The new network was a thing of beauty. A clear design, the best equipment, redundant everything. It was replacing a legacy network, one that had grown organically.
The new network was built out. Late one night the key services were cut over, and things were looking good. Everyone was happy, and we had a big party to celebrate. The project group disbanded, and everyone moved on to other things. Since the project was closed out, funding & resources stopped. Success, right?
Except…the old equipment was still running. A handful of applications were left on the old network. Some annoying services used undocumented links between the networks. Even worse, disused WAN links were still in place, and still being billed for.
The problem was that the project was officially ‘over.’ Who’s responsible for finishing off that last bit of cleanup?
I’ve seen similar things in Continue reading
