Migrated my email servers in 20 minutes yesterday from OVH (their MXs does not support IPv6, and Infomaniak was less expensive for basic email hosting), I found the documentation and the diagnostic tools of the DNS zone very clear, was a no brainer to add DKIM, SPF and DMARC (hey generate the records for you, just have to cpy paste in your zone manager and refresh the diagnostic to get a status after propagation), and autodiscovery and autoconfiguration of email clients are a nice bonus !
That's totally true, you actually have examples of unsafe capabilities delegation in the other article mentioned in the References: https://juggernaut-sec.com/capabilities/
DNS0 was launched at a time when no other EU public DNS resolver was available. Today, you have DNS4EU that is actively funded and pushed throughout the EU administration (and critical infrastructures), so I believe that the DNS0/NextDNS founders saw that there was very little differenciating factors to their proposal, and decided to shut it down.
Had they "captured" a larger marketshare in the EU while they were ahead, situation might have been different today, but in my opinion it never happened.
Which public funds ? DNS0.eu was a private initiative, from the NextDNS founders. DNS4EU is a public initiative, as mentioned in the news, and this one is still supported and actively developed.
"However, Confidential Computing is not secure enough to protect data integrity and confidentiality against a hostile administrator performing targeted, active attacks. Under such a threat model, users must avoid running on shared infrastructure operated by providers they cannot trust, and are rather encouraged to leverage Confidential Computing to increase their security posture on dedicated hardware instead."
In their current form, AMD and Intel proposals never fulfilled the Confidential Computing promises, one can hope they will do better in their next iteration of SGX/TDX/SEV, but they were always broken, by design.
Unrelated to the topic, but does anyone know if an equivalent service (à-la-carte blood testing with online booking) is available in Europe, specifically the Netherlands (or France) ?
Overall a great experience, can recommend !
