Don't think so. They used to use Cloudflare but stopped. To my knowledge, it's a single server without a database (using the filesystem as a database).

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.

It doesn't need to be crazy.

A static site on DigitalOcean's $5 / month plan using nginx will happily serve that type of traffic.

The author of https://gorails.com hosts his entire Rails video platform app on a $20 / month DO server. The average CPU load is 2% and half the memory on the server is free.

The idea that you need some globally redundant Kubernetes cluster with auto fail-over capabilities seems to be popular but in practice it's totally not necessary in so many cases. This outage is also an unfortunate reminder that you can have the fanciest infrastructure set up ever and you're still going down due to DNS.

Discord is entirely down right now, both the website and the app itself. Amusingly, a lot of the sites that normally track outages are also down, which made me think it was my internet at first. Downdetector, monitortheinternet, etc. Lots of other big sites that are down: Patreon, npmjs, DigitalOcean, Coinbase, Zendesk, Medium, GitLab (502), Fiverr, Upwork, Udemy Edit: 15 min later, looks like things are starting to…

Kudos to the people at Discord. Just a few minutes after I got disconnected they already tweeted about the issue. Some minutes later and they have a message in their desktop app confirming it's an issue with Cloudflare. All while Cloudflare's statuspage says there are 'minor outages'.

As a percentage of total traffic, a 'minor' outage for Cloudflare probably equates to a significant outage for a non-trivial amount of the internet.

It will also be especially noticeable to end-users, because sites using Cloudflare are typically high-traffic sites, and so a 'minor' issue that affects only a handful of sites is still going to be noticed by millions of people.

Would IRC be down?

>Holy crap I am thinking either there is some magic or everything we are doing in the modern web are wrong. 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. It's a lot. edit: I see that there are already a bunch of other comments to this effect. I think you're comment is really going to bring out the old timers, haha. From my perspect…

You know, it should be even better than it was in the past, because a lot of heavy lifting is now done on the client. If we properly optimized our stuff, we could potentially request tiny pieces of information from servers, as opposed to rendering the whole thing.

Kinda like native apps can do(if the backend protocols are not too bloated)

You have to remember there's a lot of seconds in a day, that's only 60 qps.

True, but this is why it shouldn't be bashed either. When you need it, you need it (cue very complex enterprise applications with SLA requirements).

That's why we have this bloated over-engineered multi-node applications: People just underestimate how fast modern computing is. To serve ~2^6 requests/sec is trivial.

It's easily served by a simple server.

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.

The username is embedded in the page, so you can't do full caching unfortunately. But the whole content could be easily cached and concatenated to header/footer.

ówò

This was a coordinated attack that took down a bunch of services all at the same time: https://downdetector.com/ https://twitter.com/KEEMSTAR/status/1284240539437740033 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.

Keemstar? Not reliable source. The dude has no idea what he is talking about.
