Yerevan, Armenia: Cloudflare Data Center #103
In the coming days, Cloudflare will be announcing a series of new data centers across five continents. We begin with Yerevan, the capital and largest city of Armenia, the mountainous country in the South Caucasus. This deployment is our 37th data center in Asia, and 103rd data center globally.
History
Yerevan, one of the oldest continuously inhabited cities in the world, has a rich history going back all the way to 782 BC. Famous for its cognac, lavash flatbread, and beautiful medieval churches, Armenia is also home to more chess grandmasters per capita than most countries!

The newest Cloudflare deployment will make 6 million Internet properties faster and more secure, as we serve traffic to Yerevan and adjoining countries.
If the Cloudflare datacenter closest to the Equator (to date) was Singapore, the next deployment brings us even closer. Which one do you think it is?

ARP, ARP Inspection, ARP Types and Deployment Considerations
Layer 2 security – ARP and ARP Inspection Introduction This article is the second of our layer 2 attacks identification and mitigation techniques series, which will be a part of a bigger series discussing Security Infrastructure. Dynamic ARP Inspection relies on DHCP snooping technology explained in the previous article. It’s strongly recommended to […]

Rough Guide to IETF 98: Internet Infrastructure Resilience
Let’s look at what’s happening in the area of Internet infrastructure resilience in the IETF and at the upcoming IETF 98 meeting. My focus here is primarily on the routing and forwarding planes and specifically routing security and unwanted traffic of Distributed Denial of Service Attacks (DDoS) attacks. There is interesting and important work underway at the IETF that can help address problems in both areas.

Middleboxes and the End-to-End Principle
The IP suite was always loosely grounded in the end-to-end principle, defined here (a version of this paper is also apparently available here), is quoted in RFC2775 as:
The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the endpoints of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible. … This principle has important consequences if we require applications to survive partial network failures. An end-to-end protocol design should not rely on the maintenance of state (i.e. information about the state of the end-to-end communication) inside the network.
How are the Internet and (by extension) IP networks in general doing in regards to the end-to-end principle? Perhaps the first notice in IETF drafts is RFC2101, which argues the IPv4 address was originally a locater and an identifier, and that the locater usage has become the primary usage. This is much of the argument around LISP and many other areas of work—but I think 2101 mistates the case a bit. That the original point of an IP address is to locate a topological location in the network is Continue reading
