This inspired me to actually look at my CloudFlare stats, and I realized it's not caching some of my HTML pages even though I had page rules setup to cache everything. I use a static site generator, and it's never been an issue at this point (nobody has any reason to DDoS me). But this is a good motivator to fix that up. I've been procrastinating on fixing a few things on my site, so I'm adding this to the list when I update it. I might also setup the CloudFlare Tunnel at the same time.
