It's also a Python 3 instance running Django/Wagtail/Puput, and all blame goes to me for poor coding. If anyone reading this happens to be a Wagtail & Render expert and wants some short contract work fixing my code, please reach out (arussell@shawkeller.com)!
I don't know the requests/second, but at peak on Google Analytics it said that 300 people were on the site "right now" -- unsure of what that corresponds to. ~5-10 reqs/s roughly?
Also note that render.com puts Cloudflare in "front" of the nodes automatically, which helps with some caching.
(I'm unaffiliated btw, just moved to them from Heroku and have been happy to far)
Hardly effective for gauging HN readership, given the abundant use of ad blockers. Based on no evidence whatsoever, 100x that and you should have a reliable estimate.
