    #CDN

    When my SSL cert MaxCDN was expiring on my personal site I decided it was a good time to revamp some things. Since GitHub Services is depreciated I can no longer have #CDN cache purges automated among other things. So I decided on the following: GitHub Pages, Netlify, Let's Encrypt and Jekyll. Staying the same was Bootstrap, jQuery, Grunt & #GoogleFonts.

    What's awesome about GitHub Pages is that it has a #CDN (Fastly) built-in and anytime you push to master, it purges the cache instantaneously without you have to do anything special. Netlify is magic, I highly recommend it to anyone using #StaticSiteGenerators.

    For the most part, everything went smoothly. The only things I had issues with were the following:

    • If you want to point www to GitHub Pages you need to rename the repo to www
    • If you edit something in the _config.yml you need to restart bundle exec jekyll s or changes won't show
    • I had to disable the Grunt htmlmin module. I replaced it with Jekyll layout that compresses HTML for #webperf

    Last but certainly not least, I made a donation to Let's Encrypt. If you use their service consider doing it too: https://letsencrypt.org/donate/

    Platform Update: we’ve been using the Performance Test tool provided by KeyCDN for a long time in combination with Pingdom's similar tool and the #WebpageTest and #GoogleInsight - we decided to test out KeyCDN for static asset hosting. The results for the endpoints were superfast - almost 200% faster than CloudFlare in some tests and 370% faster than imgix . So we’ve moved Washington Brown from imgix for hosting theme images, to KeyCDN for hosting all images and static assets (Font, CSS & JS). There’s a few things that we like about “Key” apart from saving $6 a month on the monthly minimum spend ($4 vs $10 for imgix). Key allow for a custom CNAME (no more advertising imgix.com in domain requests and possible SEO improvements - and easier to swap to another host down the track). Key allows JPEG/WebP image requests based on clients ‘accept’ http headers - imgix required a ?auto=format query string on each image resource request - which can break some caches. Key allows for explicitly denying cookies to be set on a zone/domain; cookies are a big strain on limited upload bandwidth so to be able to force these off is great - Cloudflare adds a cookie to every header… for “performance reasons”… but remember “if you’re getting a product something for free…”

    Review ofKeyCDNKeyCDN

    Using it with my webforum (9000 Users/Month / 600.000 Requests) Easy to integrate with existing documentations for all big applications, free ssl support with let's encrypt or own certificate. Ability to use own domain (like cdn.yourdomain.org). You only pay for that what you're really using (pay as you go).

    Using KeyCDN already a little bit more then one year, i love it. Loadspeed improved heavily (without: 2,5-4s | with (0,5-1,2s).

    Support is very fast and helpful in any situation.

    And the most important thing: cheaper then others. while being much faster.

    I can only recommend everyone to use KeyCDN.

    But please keep this in mind, unused credits will expire after one year if there wasn't a payment for more than a year but you can retain them with any payment for another year before the expiry.

    Review ofKeyCDNKeyCDN

    KeyCDN is a simple-to-use and reliable solution to decrease page load times around the world. In particular, I enjoy the simplicity of the dashboard provided, the CMS integration documentation, custom sub-domain configuration, and Let's Encrypt support.

    As an individual user, I use KeyCDN for a variety of different personal projects, some of which may experience high traffic at peak times. I have never once had an issue with the KeyCDN service and it has served me well over the past year.

    My one and only issue with KeyCDN is that there is a minimum purchase requirement and that the credits purchased will expire after one year. Still, one could rationalize KeyCDN as a yearly subscription service this way and it would still be a good deal for those who need a reliable CDN provider.

    Review ofKeyCDNKeyCDN

    Turned out to be the best CDN of the ones we tried (including CloudFront, CacheFly, and MaxCDN). It's by far the best modern, well designed, and easy to use interface. It seems to have every feature we could need, including SPDY support (which CloudFront still lacks), an API that allows easy free cache invalidation, HTTPS SNI, and real-time logging.

    It didn't seem to be very fast at first and we almost stopped using them, but it turns out they have an odd quirk where they don't cache pages that don't set a Content-Length header (which PHP pages normally don't). Once we set up a work-around for that issue, it worked very well. Hopefully that's an issue they can fix on their end eventually.

    Review ofKeyCDNKeyCDN

    The ability to fine tune the configuration of each zone to a specific business goal. The robust set of features available at no extra cost such as: HTTP2, Custom SSL, GZip Compression, HLS optimisation. Quick addition of latest technologies such as the Brotli compression algorithm. Still have one minus, is limit of 5 zones only. Very recommend to use

    Review ofFastlyFastly

    In addition to having a great service, a powerful API and a perfect uptime the one thing that's really awesome about Fastly is their support. They respond really fast, are very knowledgeable, and do everything they can to help you with your problem (and that includes 1-to-1 chat on irc, skype/hangout call, etc.). Such a great experience.

    Review ofKeyCDNKeyCDN

    I was using MaxCdn for a few years and found it too expensive for my low traffic wordpress sites. Then I found KeyCDN and found all the same features and benefits for half the price. I have been pretty happy using KeyCDN and switching over to them has been painless.

    Review ofFastlyFastly

    Incredible. Lets us cache dynamic pages. Makes other CDNs feel like unwieldy beasts. Support is second to none.
