It's amazing that posting this on HN has not melted it down. Are you using an edge CDN like Cloudflare to provide caching?

Sry, not my blog just thought it's interesting

It's a static file being served, 32MB RAM nginx instance can handle well past HN traffic for something like that

  It uses darkhttpd https://unix4lyfe.org/darkhttpd/ https://unix4lyfe.org/darkhttpd/

    The blog post does state they are using darkhttpd but the network request for the blog post says "Server: nginx". Does darkhttpd use nginx inside or something?

      My assumption is reverse proxy via USB localhost

      Author here! I'm serving a load of different services on that domain, which are all behind nginx.

According to a Maxmind Geoip lookup, both ip4/ip6 belong to Telia Eesti ISP, so probably no CDN caching.

if it's pure static you can easily server thousands and thousands of request per second no problem.

  This website returns 40.5 kB from nns.ee host (with CSS and SVG). 1000 users per second requires 40.5 MB/s or 324 Mb/s connection. Author mentioned that his device provides 10 Mb/s throughput. So realistic number is serving 30 users per second. For some reason his main.css is not compressed, so that would be the first thing to optimize.

    Looking at the network requests, the fonts are being served from Google api so not a problem for this. The CSS on the other hand has TONS of comments which can be gotten rid of and minimized.

      You're right, removed part about fonts.

Perhaps I'm not being very generous, but I'm often kinda surprised when sites do meltdown from the HN effect -- although I recognise it depends on a lot of factors.

  Seems like a lot of times the meltdown is just conservative rate limits on linux shared hosting. It's too bad because a lot of times it happens to sites that are getting their first substantial exposure.

  It usually seems to be stock CMS platforms that melt down. Where generating a page means a bunch of database queries.

Seems like it’s currently melted right now. Edit: ah, not. Looks like it’s reachable from my landline (which is IPv4 only) but not from my 4G connection (which has IPv6).

What truly melts sites posted on HN is inevitabile reddit post that follows.

It's returning headers with Etags (I don't think darkhttp does those) and a "Server: Nginx" header. So maybe he put a proxy in?

I mean it did take a few seconds to load, so there's at least some effect.
