Edinburgh: 139th Cloudflare city
Our newest data center in Edinburgh expands our current total to 139 cities globally with a Cloudflare deployment. It also brings our UK total to 3 cities, after London and Manchester.
The city
Edinburgh is the capital of Scotland, located in the Lothian region. It has been recognised as the capital since the 15th century, and is the home of the Scottish government, parliament and supreme courts. It is a city of many hills, with important landmarks such as Edinburgh Castle being built at the top of a hill.

Culture
One of the most famous events held each year in Edinburgh is the Fringe Festival, which is reported to be the world's largest arts festival. Many famous comedians have made their big break at this very festival.
Building a community
The internet community in the UK is very well established, but mostly concentrated on London and Manchester, with a heavy emphasis on London. By deploying in Edinburgh we're encouraging ISPs to regionalise their traffic, away from just London. We're connected to IXScotland, and are actively seeking to peer with other connected networks, to help build the peering community.
Regional expansion

Presentation and Video: Real-Life Automation Wins
The networking engineers attending the Building Network Automation Solutions online course created numerous amazing automation solutions, most of them already deployed in production networks.
I described some of them in my Troopers 2018 Real-Life Automation Wins talk. The presentation is online and the video has been published on YouTube a few days ago. I hope you’ll find it as inspirational as the Troopers attendees did.
Did you create an awesome automation solution? I’d like to hear about it!

IETF 101, Day 5: All Sorted, Innit?
This week is IETF 101 in London, and we’ve been bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. Friday is only a half-day, but there’s still a couple of interesting sessions to wrap-up the week.
NOTE: If you are unable to attend IETF 101 in person, there are multiple ways to participate remotely.
Homenet starts at 09.30 GMT/UTC, and has the Homenet profile of the Babel routing protocol currently in IETF Last Call. Other drafts being discussed include the Simple Homenet Naming and Service Discovery Architecture, Outsourcing Home Network Authoritative Naming Service, and DHCPv6 Options for Homenet Naming Architecture.
The remainder of the agenda will be a discussion about Homenet security in relation to the home perimeter, HNCP and Babel, as well as appropriate trust models and how to establish trust.
ROLL continues from where it left off on Thursday morning, also starting at 09.30 GMT/UTC. There are several drafts being discussed dealing with the issues of routing over resource constrained networks where limited updates are possible.
So that brings the IETF in London to a close, and hopefully we’ve also given you a bit of an Continue reading

Cebu City, Philippines: Cloudflare’s 138th Data Center
Cebu City, the second most populous metro area, but oldest city in the Philippines is the home of Cloudflare’s newest Data Center.
Located centrally in the Philippines, Cebu has had a long standing tradition of trade and business activity, the word itself “Cebu” meaning trade. It’s central location brings excellent coverage to central and southern Philippines, while our existing location in Manila, serving the Manila Metro and northern Philippines.

Lock-In And Enterprise IT – Video
Vendor lock-in isn't necessarily a bad thing if you know what you're getting into. But there are areas where vendors actively promote lock-in to capture unearned profits and control partners. Here's what to look out for.How Many Bandwidths Does An SD-WAN Need? – Video
Note: This article was first published at Packet Pushers.net on March 5, 2018 I was preparing for a podcast and started comparing the complexity of a private vs. public WAN. I doodled some diagrams and realized that using Internet bandwidth for SD-WAN to replace private bandwidth is actually simpler. Perhaps because the familiar is always […]
Playing with Arista eAPI – Dynamic VLAN Assignment-ish
A note
Before we get started, let me first say that just because we can, doesn’t mean we should. I got a request to show an example of how dynamic VLAN assingment based on mac-address could work and this is the results of that request. Before anyone takes this code and runs with it, let me first say that you really need to think about whether or not this is a good idea for you and your organization.
If you want dynamic VLAN assignment, there are other ways to accomplish this and I would encourage you to look into them before going down this path.
That being said – It was a fun little project and I wanted to share it with you all.
The Project
For this project, the goal is to write a simple script to help us automatically assign the right VLAN to a host based on the MAC address of that host.
Now we all know there are different ways to do this, like pure mac-authentication using a RADIUS server, or even using a mac-based VLAN configuration, but that wouldn’t be as fun as trying to get this work with Arista’s eAPI now would it?
