"The outage was related to DNSSEC signing. During the period described, incorrect DNSSEC signatures were propagated."
"The outage is linked to a routine, scheduled key rollover. During this process, non-validatable signatures were generated and distributed."

Nice writeup on a session cookie exposure vulnerability, but also on the importance of having strict CAA DNS records

Seit gut einer Stunde sind viele Webseiten mit .de Domains down:
Der Grund liegt diesmal bei der DENIC herself. Die DENIC ist die oberste Domain Verwaltungsstelle in Deutschland, bzw. für .de Domains.
"Investigating
It seems like the fault is related to DNSSEC issues with "de" domains on a registry level.
Further information from DeNIC can be found at https://status.denic.de/
Due to a fault, there is currently limited availability to the recursive DNS resolution for "de" domains."
Heisst soviel wie, die Namensauflösung von .de Domains hat aktuell ein Problem. Sprich, wenn ein Browser nach der Domain www.bge.de fragt, dann kann der DNS nicht zu einer IP auflösen, die nötig ist, um den Request an den richtigen Server zu schicken.
Meine privaten seiten mit .de domain sind ebenfalls alle down.....

Den gestrigen Di.Day habe ich zum Anlass genommen, meine digitale Unabhängigkeit noch einmal massiv auszubauen:
Ab sofort läuft bei mir auf einer kleinen Hetzner VPS ein AdGuard und ein Unbound DNS mit DNS over TLS. Jeglicher Netzwerktraffic der durch meine OPNsense und dann durch die Fritz!Box nach aussen geht, geht per DNS over TLS über meinen eigenen DNS mit entsprechenden Blocklisten.
So bekommt Vodafone nicht einmal mehr mit, welche Webseiten besucht werden.

@aura@gts.foxsnuggl.es @EUCommission@ec.social-network.europa.eu just ask @MOGiS@mastodon.social and everyone else who was insulted as "[…] hardened pedo-criminal […]" by that #TechIlliterate #Cyberfascist for being able to change #DNS settings.
I still demand a personal apology - WITH INTEREST from #Zensursula!

It's really a.missed chance by #Samsung that they don't use 123.45.67.89 as their own #DNS resolver & default for their devices.
Cuz they actually have that one allocated by #APNIC and #WHOIS literally says it's in #Gangnam! Don't believe me? Look it up!

I don't trust my ISP or the government above it.
I think everyone here today doesn't trust their ISP and government.
Use a #VPN or #TOR,Your ISP will only know the destination point, all traffic will be encrypted through a #tunnel
You said you installed a router. How did you configure the modem? In Full Bridge?
Also start changing your #DNS, don't use your ISP's default ones

DNS leak protection is a security feature in VPNs that forces all web browsing queries (DNS requests) through an encrypted VPN tunnel, preventing them from being exposed to your Internet Service Provider (ISP). It prevents hackers or ISPs from seeing your browsing history and location, ensuring your traffic stays private and secure. https://windows101tricks.com/what-is-dns-leak-protection/
What is DNS leak protection? It’s a VPN feature that keeps your DNS requests inside the encrypted VPN tunnel and away from your ISP’s DNS servers.
What is a DNS leak in VPN? It’s when your DNS queries escape the VPN tunnel and go to your ISP’s DNS servers, revealing the websites you visit.
How DNS leak protection works: It routes all DNS traffic through VPN DNS servers, blocks DNS outside the tunnel, and may use firewall rules and a kill switch.
How to test DNS leak in VPN: Connect to your VPN, visit a DNS leak test website, run a test, and check if the DNS servers match your VPN server location.
Does VPN prevent DNS leaks? Only if the VPN is designed with proper DNS leak protection and configured correctly.
