I write up some of my advice on surviving DNS outages as it seems timely #AWS #DNS https://adrianco.medium.com…

The Internet is down…. It was DNS, again
One of the common ways web services fail is problems with DNS. I’ve talked about how to harden systems against DNS related outages before…

I had to migrate my #DNS today, and Hurricane Electric is such a pleasurable return to 90s.
Website obviously designed by a backend engineer. Has only tables and buttons. Buttons work and do things. It's fast. It support features fancy sites do not support. On top of it, free.

#DNS trivia, especially for those have ever used the "It was DNS" meme. What is wrong with this (real) dig response and what is the likely cause? AI probably won't help you.

I really dislike the "it's always DNS" trope because frequently it's something else, but #Kroger's shit was fucked all day and it was definitely #DNS. I think they have it loosely functional now, though there are so many nested CNAMEs the

If you ever want to hear your family come to life. Take down the home DNS server lol. #DNS

Why am I smelling #DNS again :mortysmile:

The standalone Proxmox server is basically done at this point, all three DNS servers are online and secure, the Tailscale VM is online after completely forgetting that it was running on one of the Raspberry Pis, and the `authentik` instance that I'm gonna need to work on tomorrow.

So I was pretty enthusiastic about #DNS4EU at first.
Then I've discovered it blocklisted some random pastebin. Well, it happens. I mean, pastebins frequently get into trouble because of people pasting random shit. So I've filed an unblock request. I've suddenly got a mail to confirm registration in some random company's system — I suspect it was related to DNS4EU, but no clear indication. I've ignored it.
Then they've blocklisted my mail provider, for no apparent reason. It's still blocked. I've switched to the "unfiltered" version to be able to access my mail again.
Today I've gotten a mail via my backup MX. My main MX is up. My educated guess is that sysadmins using DNS4EU now get my mail redirected to their "site blocked" server. Isn't that great?
PS. Maybe if more people filed unblock requests for "poczta.ftdl.pl", it would help. It's a non-profit e-mail provider.

Heute hat die Welt mal wieder gemerkt, wie das so ist, wenn man von US-amerikanischer IT abhängig ist, oder?
Wie hoch ist die Chance, dass die Welt nach diesem zichsten Ausfall von großen Anbietern endlich mal etwas lernt?

This is not the first time for #Microsoft #DNS-related problems. As I recall, the first one I remember from 2001 had something to do with their authoritative name servers residing on the same IP4 /24 that had an access or availability problem.
It was a rookie mistake even then, and they were …

It's never a good sign when your Monday morning feed is full of #dns and #aws memes. Monday's eh? 🤷

Oh my, @… is fast ! Faster than Cloudflare or Google. With average response time of 12 ms.
Where cloudflare was 22 ms
And Google shited with 232 ms 😆

Have you noticed that when the blame #DNS meme starts flying the root is perfectly operational, there is rarely a mention of the big registry operators, BIND, Unbound, Knot, and PowerDNS are absent the conversation, and many who can craft a reasonable dig query are getting responses from local and public resolvers to debug?
Even with all the misconfiguration, added complexity on top of it, a…

Hey #askfedi one of my family members android device is making these DNS quarries. I can't fine the culprit. I don't see any weird property apps install on it. Any idea who could be doing this?
Edit: I found syncthing is doing this. But why? Why syncthing needs this? And what is stun?

On 2025-01-19 there were two "biden" names, bidenlibrary and bidenwhitehouse. Not so unusual. Associated names for Obama and Trump were also there and remain still. These are exec branch names but the agency responsible for them is the National Archives and Records Administration (NARA).
As of today, there are four additional "trump" labels in the …
