Aside from this one issue, is switching to 1.1.1.1 a good idea in your guys experience? Right now I just realized I hvae the DNS for my ISP which is probably how they inject bullshit 404 pages full of ads. What is the fastest/best public DNS in your guys experience?

I've been pretty happy with 1.1.1.1 (before now). Might be worth using something like 8.8.8.8 as a backup (Google).

You could also use 9.9.9.9 as your backup, if you're avoiding Google (https://www.quad9.net)

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.

Agreed, but the real problem is DDoS and nobody seems to know how to globally solve it. Fighting DDoS is expensive, so you see consolidation. It's well and good to live in a tiny farming town but when raiders start attacking every week, those castle walls and guards start to look really appealing.

That's what we get for externalizing costs. It's not hard to track down sources, but network operators usually let it be, hence the incentives are probably counter-productive.

Why not you? Just don't use CF. The more people stay away from CF, the better.

I feel like for a lot of sites CF & CDNs are the only way to survive Reddit/HN/etc - do you disagree? I definitely agree in concept with you, but then i think back to how frequently script kiddies took down sites ~10 years ago, or w/e. I feel like what has changes is the massive CDNs in front of so many sites. So while i do want a better solution, i'm not sure what it looks like. Thoughts?

Some kind of decentralized CDN in theory.

This was a problem with our backbone network; wasn't caused by an attack. The effect was regional and not global. Naturally, we'll write it all up.

Was it a problem with a provider you use?

Looks like problem with one of our large routers in Atlanta.

Does it really matter? If you're small, who cares if you go down for half an hour? What, you'll make $0.02 this hour instead of $0.05? If you're big, you can afford your own infrastructure. Stick a few servers in a few colos around the world and you'll have better uptime than CF and friends anyway.

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. Edit: The number is from Dang [1] > These days around 5.5M page views daily and something like 5M unique readers a month, depending on how you try to count them. [1] https://news.ycombinator.com/i…

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…

In-memory databases? That's amateurish. Time to make a service that runs out of ymm registers.

I've been using https://nextdns.io/ - works fast and most importantly blocks a bunch of adds (user configurable), so makes browsing on mobile much nicer.

Ancedotally the interenet seems faster.

I don't understand why the big companies don't always have at least two CDN providers, so they can failover to another one if something like this happens. I know a lot of big companies do, but I am always surprised when you see ones that don't.

the DNS itself is not as easy to duplicate across multiple provider, with CF DNS down having a backup CDN wouldn't have helped

This isn't true... you can certainly do redundant dns with automatic failover between providers. Just set up NS records pointing to different providers.

A lot of unusual internal traffic seems to be around Thailand (you might have to select "UNUSUAL"): https://www.digitalattackmap.com/#anim=1&color=0&country=ALL...

been pretty large numbers from thailand this month according to that tool
