So HN is serving 5.5M page view daily (excluding API access ) on a single server without CDN and without a database? Holy crap I am thinking either there is some magic or everything we are doing in the modern web are wrong.

A lot of modern web technology is inefficient for the sake of being ergonomic. Here's what Hacker News looks like: https://github.com/arclanguage/anarki/blob/master/apps/news/...

From an old-school lisper perspective, the code seems perfectly ergonomic to me.

It's ergonomic in a very lispy way but perfectly reasonably so from the POV of that aesthetic.

Their dns record points to only one IP (209.216.230.240) that goes to M5 Computer Security

ówò

This was a coordinated attack that took down a bunch of services all at the same time:

Update: People are accusing me of using KEEMSTAR as a source and have somehow missed the link to downdetector.com, which keemstar is looking at.

It really defies the original vision of the internet to have so many services depend on a single company. Almost every news site I was reading dropped off at once. I thought for a second that I lost internet in my own house.

I consider DNS and the way how top level domains are handled to be one of the weakest parts of our current Internet design. We REALLY need a truly decentralized, distributed DNS system that is not owned by private entities.

I'm down for passing around a GPG signed hosts2.txt file. Let's get started.

Out of curiosity, done HN use any CDN or other way of DDOS protection? dang?

It's a hosting company in San Diego: https://www.m5hosting.com/

I host a dedicated server there (running https://www.circuitlab.com/) and when I traceroute/ping news.ycombinator.com, it's two hops (and 0.175 ms) away :)

Spin up an apache installation and see how many requests you can serve per second if you're just serving static files off of an SSD.

Fairly Dynamics with Huge number of users and comments. But still, I think I need to rethink lots of assumption in terms of speed, scale and complexity.

There is some caching somewhere as well, probably provides a bit more boost.

I've been at my work laptop (not logged in) and found something I wanted to reply to, so I pulled out my phone and did so. For a good 10 seconds afterwards, I could refresh my phone and see my comment, but refresh the laptop and not see it.

Huge numbers of users don't really mean that much. Bandwidth is the main cost, but that's kept low by having a simple design.

Serving the same content several times in a row requires very few resources - remember, reads far outnumber writes, so even dynamic comment pages will be served many times in between changes. 5.5 million page views a day is only 64 views a second, which isn't that hard to serve.

As for the writes, as long as significant serialization is avoided, it is a non-issue.

(The vast majority of websites could easily be designed to be as efficient.)

Not sure where your 5.5M number came from, but that's only 64 requests per second. 90 to 99% of those are logged-out users, so fully cacheable. Only a handful of dynamic requests each second remain.

Unlike Reddit, logged in and logged out users largely see the same thing. I wouldn't imagine there is much logic involved in serving personalized pages, when they don't care who you are.
