Well, if you're serving reasonable amounts of text and not including a javascript kitchen sink. I mean yes, you probably should be serving library off an edge network, but I've seen stranger.
Then that goes out the window the moment you have any media on that Pi... ISP upload speed in the US is balls.
Oh, did I mention that most ISPs in the US don't allow hosting websites? So are you putting that Pi in a datacenter?
And, I forgot to mention, what happens with you piss off some bored troll and get DDOSed?
None of what you mentioned related to "traffic to a blog post from HN front page". I am just saying "traffic from HN front page" is a poor example of things that need "scale up".
Not disagreeing all the challenges you mentioned. Just "traffic from HN front page" is so easy it is a poor example.
> but if you have a blog post that hits the front page of HN.
HN traffic is so small that unless you are using Raspberry Pi Pico, it is fine.
Your 5-year old Android phone probably can handle HN traffic just fine. (HN traffic is in a range of single-digit kilo qps).
