I don't use cloudflare DNS but google DNS and got the same problems thant everyone else The problem seems to have been resolved now, you might have made the change when they fixed it.

> I don't use cloudflare DNS but google DNS and got the same problems thant everyone else Cloudflare is also the authoritative DNS server for many services. If Cloudflare is down, then for those services Google's DNS has nowhere to get the authoritative answers from.

Except the services mentioned in the original post have a ttl of 1h. Unlikely they would all go down at the same time.

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.

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.

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/...

That's only ~60 QPS, assume it is peaky and hits something more like 1000 QPS in peak minutes, but also assume most of the hits are the front page which contains so little information it would fit literally in the registers of a modern x86-64 CPU.

Even a heavyweight and badly written web server can hit 100 QPS per core, and cores are a dime a dozen these days, and storage devices that can hit a million ops per second don't cost anything anymore, either.

1M queries per day is ~10 queries per second. It's a useful conversion rate to keep in mind when you see anyone brag about millions of requests per day.

I'm surprised so many people still use them. They took my business down (along with half the internet) a few years ago and I learned that they were to large of a point of failure.

Crazily, my local name resolution started failing, because I have these names servers: 192.168.0.99, 1.1.1.1 and 8.8.8.8. The first does the local resolution, but macOS wasn't consulting it because 1.1.1.1 was failing?? Crazy. When I removed 1.1.1.1 from the list, everything started working.

DNS over HTTP might bypass your local nameservers.

What was failing was ssh to a local host. I can't imagine that Brew ssh uses DNS over HTTP.

>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…

That is great ! :D

>It's a lot.

Well yes, but HN isn't really static though. 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.

It is certainly doable , PoF was running lot of page views famously of a single IIS server for a long time .

HN is written in a lisp variant and most the stack is built in-house , it is not difficult to imagine efficiency improvements when many abstraction layers have been removed from your stack .
