I remember Jason telling me about this weird service worker caching behaviour a little while back. This piece is a great bit of sleuthing in tracking down the root causes of this strange issue, followed up with a sensible solution.
An excellent, thorough, even-handed analysis of AMP’s performance from Tim. The AMP format doesn’t make that much of a difference, the AMP cache does speed things up (as would any CDN), but it’s the pre-rendering that really delivers the performance boost …as long as you give up your URLs.
But right now, the incentives being placed on AMP content seem to be accomplishing exactly what you would think: they’re incentivizing AMP, not performance.
Medium, Twitter, Facebook and others are edge services for your content … Your platform is the origin.
An open beta of Smashing Magazine’s redesign, which looks like it could be a real poster child for progressive enhancement:
Great news from Cloudflare—https endpoints by default!
This means that if you’re planning on switching on TLS for your site, but you’re using Cloudflare as a CDN, you’ve got one less thing to change (and goodness knows you’re going to have enough to do already).
I really like their reasoning for doing this, despite the fact that it might mean that they take a financial hit:
Having cutting-edge encryption may not seem important to a small blog, but it is critical to advancing the encrypted-by-default future of the Internet. Every byte, however seemingly mundane, that flows encrypted across the Internet makes it more difficult for those who wish to intercept, throttle, or censor the web. In other words, ensuring your personal blog is available over HTTPS makes it more likely that a human rights organization or social media service or independent journalist will be accessible around the world. Together we can do great things.
