I am pretty sure that this is the thread that introduced me to it:
https://news.ycombinator.com/item?id=10681851Unfortunately, web.archive.org didn't grab an https version of my main site from around that period. My oldest server build script in my current collection does have the following note in it:
**Get the current version of dehydrated from https://github.com/dehydrated-io/dehydrated **
(Dehydrated was previously found at https://github.com/lukas2511/dehydrated)
...so I was using it back when it was under the lukas2511 account. Those tech notes however were rescued from a long-dead Phabricator installation, so I no longer have the change history for them, unless I go back and try to resurrect its database, which I think I do still have kicking around in one of my cold storage drives...
But yeah, circa 2015 - 2016 should be about right. I had been hosting stuff for clients since... phew, 2009? So LetsEncrypt was something I wanted to adopt pretty early, because back then certificate renewals were kind of annoying and often not free, but I also didn't want to load whatever the popular ACME client was at the time. Then this post popped up, and it was exactly what I had been looking for, and would have started using it soon after.
edit: my Linode account has been continuously active since October 2009, though it only has a few small legacy services on it now. I started that account specifically for hosting mail and web services for clients I had at the time. So, yeah, my memory seems accurate enough.
