I was recently wondering why I had stopped serving both HTTP and HTTPS on my sites. Ever since Let's Encrypt, my sites have been HTTPS only, but recently the people defending the needs of old tech made me think we could have both. I suspect I stopped having both because search engine optimization suggested it'd be better for page-rank if there was only a single, canonical URL per page.

Now that I've basically decided to have my site without search engines, I might as well enable HTTP again, even if that means that some people get ads added to the web pages by their ISP. It's up to them, now: HTTP can be used by old hardware or frugal software where as the security (integrity) conscious can use HTTPS. Or am I forgetting something important?
