Yeah I would definitely try either turning off CloudFlare, or switching to some different CDN that provides a CloudFlare-like service. My gut says its CloudFlare, because what I learned from CloudBleed is that they've engineered a really complex system to get good performance from a bad architecture, and complex code is prone to failure. https://en.wikipedia.org/wiki/Cloudbleed https://en.wikipedia.org/wiki/Cloudbleed It might also be on the hosting end, but hosting setups are somewhat "commoditized" now, and probably less tuned for performance, so I would expect fewer exotic, unreproducible bugs. Personally I just use Dreamhost, and my blog has been on HN many times, including the #1 spot, and it's worked fine. You don't need a lot of technology to serve static content these days. Computers are fast.
