Looks like it's back. No longer getting issues with 1.1.1.1 and domains are being resolved!

Not for me, `dig @1.1.1.1 google.com` is returning SERVFAIL still. Their anycast config may be broken in some way (ie. the backends for some regions are down, but still advertising routes)

Resolved as of a minute ago, still having an issue now?

DDoS has two components: a) complexity: trick your servers into doing something hard b) volumetric: overwelm your servers with a lot of traffic c) volumetric part two: overwelm your servers with a lot of requests, so you respond with a lot of traffic A and C are things you can work on your self --- try to limit the amount of work your server does in response to requests, and/or make resource consuming responses requi…

I'm not very familiar with DDoS protection strategies. Can you please elaborate on what is meant in (c) by "make resource consuming responses require resource consuming requests"?

Make people login before doing a search is a common example for forums. Search is hard, unauthenticated search will bring low end forums down, so they make you create an account and login.

That sort of thing.

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.

I had this same reaction. Definitely feels like most of what we’re doing with “the modern” web is probably wrong.

You can serve a lot of flat files from a properly configured server in 2020. It's just that most people don't bother trying.

Well, it's not magic. So, the other one.

I doubt this is physically possible. I think they have distributed edge caches for pages with short TTLs.

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…

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.

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).

We've been telling this for a while now...
