Thanks. There are many numbers in those charts that I don't understand. I was hoping that HN community will help: Why there are so many 405 (method not allowed) errors? I get this from, e.g., Twitterbot. Am I right? If someone GETs HTML and doesn't CSS then it's a robot? Why so many robots (web crawlers)?

Could some of those people have cached css files from a previous page view?

How were your cache control headers set up? Most browsers cache CSS files very aggressively (not even requesting a HEAD for them) once they've been loaded once - hence the common use of query strings or asset paths for CSS to ensure users get new versions on new deploys.
