    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/

    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.

    Combining the speed and reliability of multiple CDN's (plus additional servers) - this is the future of content distribution

    Review ofFastlyFastly

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