Hey! We’re back. #itsalwaysdns

It's always DNS.
I can not check in to my flight tomorrow because Lufthansa's DNS responds with NXDOMAIN due to denial of existance responses.

Did I silently drop the MX record for my mailserver? Somehow, yes.

Migrating DNS for my infra.

This definitely won’t cause any downtime issues.

The Problem Wasn’t NTP. It Was DNS. Obviously! More tales from the homelab!I noticed another error in Pi-hole after upgrading to v6, but ultimately zero issues throughout the house. I don't trust these things and actually learned something I proba...

Pi-hole v6 upgrade sent me down a fun rabbit hole.
NTP errors, nothing actually broken, and then the realization: I let Pi-hole depend on itself. DNS ate time.

From Pi-hole v6 Log Anxiety to DNS Zen: The Real, Slightly Messy Journey to Unbound This post starts the way a lot of my homelab stories start: Everything worked, but my brain refused to accept it due to log files indicating there was a problem. What came about was an interesting jou...

Pi-hole v6 didn’t break DNS. It did (however) expose assumptions I didn’t realize I was making. This is the story of log anxiety, recursive queries, and why boring DNS is the best DNS.

I feel obligated to make the obvious joke: Did the person who worked on AWS get a job at Cloudflare? #itsalwaysdns

Tschuldigom' haben wir ein Cloudflare Problemchen? #itsalwaysdns #cloudflare #internetkaputt

I have managed to misconfigure /something/, /somewhere/ in Cloudflare and it just straight up refuses my query for this one singular domain name.

And I am literally at the pulling-hair-out stage.

It's ALWAYS DNS…. If your Micro$oft services are not working today… that's why.

I fought DNS over the weekend in relation to my homelab and home automation stuff. DNS remains undefeated....

#homelab #itsalwaysdns

I thought my HomeAssistant was really slow to respond sometimes. Nope, turns out DuckDNS is a bit crappy.

Switching to a different dynamic DNS provider cured a lot of the problems.

What's to be learnt from the #AXWOutage? At least this:

1. #ItsAlwaysDNS
2. Most of the so-called #IoT is stupid and should be rethought. (Ed. note: it's mostly a scheme to scrape more data about consumers to exploit & sell; not a structure to make consumers' lives better or cheaper.)

Today, an untold number of IT people are learning about DNS NCACHE aka DNS Negative Caching.

#oarc45 #lovedns | DNS-OARC Why Image is Worth Having an Eye On Barbara Jantzen (deSEC e.V.) offers a witty take on how perception—not facts—has shaped DNSSEC’s reputation and deployment. #OARC45 #LoveDNS ^RP

On day 2, I was given the opportunity to talk about how image (and not only facts) can impact the assessment of technical issues, taking DNSSEC as an example.
Fun fact: I started my talk with an impersonation… risky, but worth it in the end 😉

On day 1, my colleague Peter Thomassen presented his (and Steve Shengs) draft on DS automation guidelines, amended by the results of the previous day’s workshop discussion, and aiming at getting further feedback from the DNS community.

Den halben Tag damit verschwendet, warum meine DNS-Challenge nicht funktioniert, bis ich darüber stolpere, dass die #Netcup Server nur von intern auflösen und der Acme-Client natürlich mit ’ner irreführenden Fehlermeldung zurückkommt … Hätte ich mich mal ans alte #itsalwaysdns gehalten.

Hackers exploit a blind spot by hiding malware inside DNS records Technique transforms the Internet DNS into an unconventional file storage system.

It's always DNS and honestly, this doesn't surprise me. A company I used to work for used DNS to pass back performance and operational information from their on-prem customer devices. It was only a matter of time before bad actors used DNS to send files. #dns #badactor #security #itsalwaysdns

Yay I think we're back! Instance was down.
