GitHub’s Joe Williams discusses mitigating security threats
At Fastly Altitude 2015, Joe Williams, a computer operator at GitHub, gave a talk on mitigating security threats (like DDoS attacks) with a CDN. This post is an overview of his talk, with full video and slides included.
The importance of performance monitoring
Your site's performance needs to be monitored closely, but once you start your monitoring initiative, you might find yourself drowning in an endless wave of information. This can make it difficult for you to get insight into your online systems. Here are some simple steps for performance monitoring that will produce easy-to-interpret, actionable data.
Raising $75 million to fund global expansion

Extending your application to the edge with Fastly
We often say that Fastly can easily become an extension of your app — there are three major components that make this possible: caching, control, and visibility.
Expanding our presence in Japan: Partnership and a new POP
This week, I’m in Tokyo to attend SoftBank World 2015. Today I had the honor of sharing the stage with Ken Miyauchi, President & CEO of SoftBank Corp., to make a few announcements about Fastly’s expanding presence in Japan.
How Fastly builds POPs

OSCON 2015 takeaways: open source innovation, caching strategies & more | Fastly
O'Reilly’s Open Source Convention (OSCON) is always exciting. It’s easy to feel the collaborative, open source spirit throughout the conference and the events surrounding it. This year, our team traveled to Portland, Oregon to talk shop about all things web performance.
How to fuzz a server with American Fuzzy Lop
In this blog post, I'll describe how to use AFL's experimental persistent mode to blow the doors off of a server without having to make major modifications to the server's codebase. I've used this technique at Fastly to expand testing in some of the servers that we rely on and others that we are experimenting with.
The technology that empowers real-time journalism
We’re more engaged online than ever before, especially when it comes to consuming news. If you work with online media brands, you’re well aware that the way readers engage with news events is changing.
Caching with CORS
Before diving into CORS (Cross-origin resource sharing), I need to mention JSONP, which is the other solution to getting data from a different “Origin.” In Using ESI, Part 2: Leveraging VCL and ESI to Use JSONP, Simon explains what JSONP is, and how to cache it with Fastly, using one Fastly specific feature, req.topurl. Now, with Varnish 4.1, req.top.url (note the extra period) is available, and it allows you to do the same thing with vanilla Varnish.
Fastly Engineers Discuss Coding Bootcamps | Fastly
It’s difficult to change course mid-career and educate yourself on a new subject after college has ended. For those entering the field of engineering, it often means taking coding classes or taking part in a coding bootcamp, such as those offered at App Academy, General Assembly, Hackbright Academy, and Hack Reactor.
Recap of Altitude 2015, Fastly’s first customer summit
Last week, we hosted our first customer summit, Altitude 2015, at the SFJAZZ Center. Our goal was to bring together our customers and the people who build our products to discuss web performance, Varnish, and the future of Fastly.

Q&A with Miles Ward, Google Cloud Solutions Head | Fastly
We had the opportunity to sit down with Miles Ward and chat about trends in the cloud industry, working with Fastly, and how Google Cloud Platform really sets itself apart.
Defining innovation capacity, part 2: Flexibility capacity
I believe that inflexible technology can promote an aversion to innovation. When building a stack, cost and performance are traditionally prioritized. That makes sense for immediate needs, but companies are finding that the flexibility of that stack matters in the long run.
Innovation Capacity Defined: Tech Stack Values | Fastly
Today's ideas can become tomorrow's indispensable service. This doesn't happen by magic. It takes a toolbox designed for innovative work.
The VCL Cookie Monster
This month's tip is more a theoretical exercise than anything else, just to show the power of VCL, and to explain a few regular expressions. I'm going to discuss VCL that deletes cookies.
FREAK does not affect Fastly services
Fastly is not vulnerable to Logjam — we only offer the more secure Elliptic Curve variant of the Diffie-Hellman key exchange (ECDHE), and the RSA key exchange mechanism for clients that don’t support ECDHE. Since Fastly does not offer any export grade ciphersuite options — and we do not offer the Diffie-Hellman key exchange mechanism — our services are not affected.
