[rocksdns.ovh] Interrupción temporal por IPv6

Durante la implementación de compatibilidad con IPv6, el servicio DNS quedó inoperativo durante unos minutos. Ya está plenamente restablecido.

Gracias por vuestra paciencia y por formar parte de esta beta.

(Esto es lo que tiene probar cosas nuevas en tiempo real)

Seguimos mejorando. Si notáis algo raro, avisad.

Muchas gracias por ayudar a que este proyecto siga adelante.

For anyone following along on my thrilling #DNS experiments… I’m now testing @mullvadnet’s encrypted DNS, which is offered in a few different flavors:

- regular (no blockers)
- blocks ads & trackers
- blocks above + malware sites
- blocks above + social media
- blocks above + adult & gambling

So far, all ads blocked! And the service is free, much like basic AdGuard DNS (which I'm used to). Also Mullvad is a solid, trustworthy company from everything I've read.

Only downside for me is this service is not customizable at all — so you cannot have custom allow-lists, for example. There are a tiny number of services I do need to use that, for whatever reason, are sometimes included in these blocking lists. So, yes, I do want the most robust BLOCK EVERYTHING DNS *except* for just a couple things. <tiptoes out of the room>

(Next, I will test ControlD for this reason.)

Stay tuned for more exciting adventures in… nerding out while the kids are at camp! 🤓

@qwertz
Der Aufbau von eigenen DNS-Resolvern ist ja ziemlich einfach und führt nicht zu einer Fragmentierung des DNS.

(Bei völlig unabhängigen #DNS-Rootservern, die nicht einfach Mirror vom A-Root wären, sähe das ganz anders aus.)

How much EU is in DNS4EU? :: Techlog

TL;DR: Not that much... 😒

I’ve been using @nextdns for a few days now. It’s impressively easy to set up. But… for my main use case (ad blocking), it’s not as consistent as AdGuard DNS. Many ads are getting through — even though NextDNS claims to use AdGuard DNS’s own block list. (It’s an option; I have it enabled.)

Anyway now I’m confused why the service that should be blocking MORE is actually blocking LESS.

🤔🤷‍♂️

Wydarzenia z ostatnich miesięcy pokazały nam, że fakt, iż większość technologicznej infrastruktury zależy od USA jest... ryzykowny. Na szczęście Europa "zbroi się" - ostatnio wzbogaciła sie o DNS4EU, resolver działających w ramach naszego kontynentu, który ma być częścią czegoś większego. Polacy też mają w tym udział!

Дыра в щите Cloudflare: как атака на Jabber.ru вскрыла проблему, о которой молчат c 2023

Многие помнят позапрошлогодний инцидент с Man-in-the-Middle атакой на XMPP-сервис jabber.ru . Эта история наделала много шума, но, как мне кажется, главный вывод из неё так и не был усвоен широкой аудиторией. А зря. Потому что эта атака вскрыла системную уязвимость в процессе выдачи TLS сертификатов, которая напрямую касается миллионов сайтов, особенно тех, кто доверяет свою безопасность Cloudflare. В этой статье я расскажу вам о самой уязвимости и как вы можете быть ей подвержены. В кроличью нору

#PayPal hat echt Eier! Machen TV Werbung und weisen daraufhin das die Daten bei ihnen sichert sind.
Mag sein, die Daten könnten bei ihnen sicher sein, aber warum wollen sie ALLE Daten von mir und nicht nur das nötigste an Daten? Und warum wollen sie meine Daten verkaufen, und sind die dann noch immer sicher?
Wer glaubt eigentlich was einem in jeglicher #Werbung vermittelt werden soll?
Also bei mir wird auf #DNS Ebene alles von PayPal geblockt.

Behold! The #DNA of a #strawberry! 🍓

Extracted last night by kiddo, when we went to the Long Night of the Sciences in #Magdeburg. We also removed a gummy bear and a noodle from both a watermelon and a pumpkin with the help of an endoscope, learned about CT scans and MRI, played around with guide wires and catheters in blood vessel models, learned the difference between danger and risk, played A&E doctors who had to decide what kind of medical imaging our patient needs, listened to elephant rumbles, watched a robot doodle, did an audiometric test, ate ice cream and burgers, visited the Gruson greenhouses, checked out scrap metal sculptures, and listened to Electronica at midnight with a light show. 😂 It was a long and awesome day – and night!

If there is one of those events near you, you shouldn't miss it! 😊

A hand holds a small, clear Eppendorf tube, typically used in laboratory settings. The tube contains a clear liquid, with a small amount of white, solid material settled at the very bottom and a few air bubbles visible near the top of the liquid. The background is a plain, dark grey, putting the focus entirely on the tube and its contents.

We've been hard at work the past few months!

1. Leaving the Westin datacenter in downtown Seattle and moving on from expensive co-location

2. Moving our gear to Fremont, California

3. Bringing on board a few new Advisory Board members, including @whil who has been an incredible help deploying our #Proxmox infrastructure, and @alexhaydock who has been instrumental in deploying our new #Ansible infra, new recursive #DNS resolution infra, and new #Tor exit relays in California! See: infosec.exchange/@alexhaydock/ with more updates to follow

4. Installing new co-location with some older low-power systems in Amsterdam for our self-hosted #ActivityPub infra @ disobey.net, where we just moved our #Mastodon profile to!

5. Deploying a new #XMTP node @ xmtp.disobey.net, and testing a new #DeltaChat relay!

6. Deploying some new #obfs4 private bridges for use in a country who's conducting heavy internet surveillance and censorship, blocking access to @torproject

and today is our birthday!!! we're 8 years old today ^_^ stay tuned for more updates to come!
