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.

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

Cloudflare sits in front of the entire site providing HTTP2 and HTTPS, which is particularly important due the large number of SVG images for the headings that need to be send down to the browser in parallel. Cloudflare also manages the DNS for DKIM TXT records, a dynamic root ALIAS record to the Heroku application, and GeoIP country headers.

We use CloudFlare to protect our network from breaches as well as to reduce bandwidth on the servers themselves and therefore freeing up the bandwidth for our other projects. We also use CloudFlare for instant DNS propagation across the internet where possible.

We love the free SSL and extensive CDN network. DDoS protection is a plus. Great premium features for rapidly growing projects. Cloudflare has helped us forget about silly things like asset minification and email obfuscation.

We use CF for DNS hosting, since their AnyCast DNS provides the best latency in the business, and they support DNSSEC + IPv6. We don't use the CDN or website optimizations.
