How was the state of the Internet’s routing system in 2017? Let’s take a look back using data from BGPStream. Some highlights:
An ‘incident’ is a suspicious change in the state of the routing system that can be attributed to an outage or a routing attack, like a route leak or hijack (either intentional or due to a configuration mistake).[i] Let’s look at just a few examples of incidents picked up by the media.
March 2017. SECW Telecom in Brazil hijacked prefixes of Cloudflare, Google, and BancoBrazil causing some outage for these services in the region.
April 2017. Large chunks of network traffic belonging to MasterCard, Visa, and more than two dozen other financial services companies were briefly routed through a Russian telecom. For several minutes, Rostelecom was originating 50 prefixes for numerous other Autonomous Systems, hijacking their traffic.
August 2017. Google accidentally leaked BGP prefixes it learned from peering relationships, essentially becoming a transit provider instead Continue reading
I’ve reorganized the menu on the left just a little, combining some items under “reading,” and adding a new item called “topics.” Under this new item, you’ll find collections of articles on specific topics from other sources, starting with the ‘net neutrality page and the meltdown and spectre post reformatted as a page, with some new additions. I’m always trying to find new ways to organize the information here, making it easier to find things; hopefully this is a useful change.
The virtual evolved packet core is one of the best working examples of NFV in a mobile operator network.
Disaster recovery used to be a pretty complex beast — but that isn’t really the case anymore.
Hey look, Microsoft just arrived in 2010.
For a long while now I’ve been brainstorming how I could leverage the API that’s present in the Cisco Spark collaboration platform to create a bot. There are lots of goofy and fun examples of bots (ie, Gifbot) that I might be able to draw inspiration from, but I wanted to create something that would provide high value to myself and anyone else that choose to download and use it. The idea finally hit me after I started using Zabbix for system monitoring. Since Zabbix also has a feature-rich API, all the pieces were in place to create a bot that would act as a bit of middle-ware between Zabbix and Spark. I call the bot: Zpark.
Instead of relying on Zabbix to initiate an email or SMS to alert me of a new issue, I now route all notifications through Zpark and get notified right within my Cisco Spark client. And since I have the Spark client on all of my devices, I can receive alerts no matter where I am or what I’m doing.

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. We interviewed two people – the new OSCE Representative on Freedom of the Media and a an emerging leader from Brazil, an Internet Society 25 Under 25 awardee – to hear their different perspectives on the forces shaping the Internet’s future: Harlem Désir and Paula Côrte Real.
Harlem Désir is the Operation for Security and Cooperation in Europe (OSCE) Representative on Freedom of the Media. Prior to his current position, Désir was French Minister of State for European Affairs, attached to the French Minister of Foreign Affairs and International Development, and a member of the European Parliament for three consecutive terms from 1999 to 2014.

The Internet Society: What could impact the future of freedom of expression online?
Harlem Désir: There is an ongoing shift under our feet which could result in a less open, global, and free Internet. A combination of factors, including legitimate security concerns in the fight against terrorism or the fight Continue reading

Paula Côrte Real is a 24-year-old Brazilian who hopes to help create a safe and secure Internet experience for Brazil’s youth through her involvement in several youth engagement programs. One of those, led by the Commission of Information Technology Law from the Brazilian Bar Association in Pernambuco, helps students learn how to protect themselves while using the Internet. It also tackles current issues such as cyberbullying and cyberstalking. To date, the project has reached approximately 2,000 public school students between the ages of 15 and 18. In 2017, she was awarded the Internet Society’s 25 under 25 award for making an impact on her community and beyond.

In this video, learn how to use Wireshark to examine two common causes of network performance issues.
The Internet Society continues to deepen its engagement with the Middle East by participating in the e-AGE 2017 Conference. This was held on 2-4 December 2017 at the Arab League in Cairo, Egypt, and was organised by the Arab States Research and Education Network (ASREN) and co-sponsored by the Internet Society and ICANN.
ASREN is a non-profit association of National Research and Education Networks in the Middle East that aims to connect institutes to enable access to services, applications and computing resources within the region and around the world, and to boost scientific research and cooperation amongst its members. Its mandate covers 22 countries, and it has partnered with the major regional R&E networking initiatives elsewhere in the world, including GÉANT (Europe), Internet2 (United States), CANARIE (Canada), WACREN (West Africa) and RedCLARA (Latin America). International connectivity is supported by the EU-funded EUMEDConnect3 and EUMEDGrid projects.
There were two main themes to the conference – that NRENs were access pathways to global knowledge, and that NRENs needed to distinguish themselves by doing things that were not or could not be provided by commercial ISPs. Michael Foley (World Bank) highlighted how the NRENs had played a key role in the evolution of Continue reading
It’s interesting how the same pundits who loudly complain about the complexities of BGP (and how it will be dead any time soon and replaced by an SDN miracle) also praise the beauties of intent-based networking… without realizing that the hated BGP route selection process represents one of the first failures of intent-based approach to networking.
Let’s start with some definitions. There are two ways to get a job done by someone else:

Here is the Cheat Sheet for DNS, an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.cloudpacket.com might translate to 104.27.143.238.
The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
