And the most important thing is of course people and skills. The Internet connects people, not machines.

Now, official talk from the governement, Stéphanie Obertin, minister for digitalisation. (Speaking in French except she says "open source" instead of « logiciel libre »)

« Le Luxembourg a une politique cohérente et soutenue en matière de souveraineté numérique. » Tout est hébergé dans le cloud souverain.

Bizarre, la réécriture de son titre par Wikipédia : https://fr.wikipedia.org/wiki/Minist%C3%A8re_de_la_Num%C3%A9risation

.lu, like most TLDs, use #anycast so there are actually hundreds of machines to serve #DNS queries.

Make sure you have a solid DNS setup because everything depends on it.

And connect to Internet exchange points.

(Note: DNS hosting at Cloudflare was working during yesterday's outage.)

" #DNS is a fundamental part of the Internet"

And the picture which explains DNS resolution use the current IP version (unlike most tutorials which use a 20th century version)

The example she gave of the "SIgnalgate" (reporter from The Atlantic listening to a secure US group) is a bad example: it was not a technical failure, just an human error. No protocol; software or algorithm could prevent that.

Achieving sovereignty, security and resilience: best practices and key decisions

Mostly about #Matrix https://matrix.org/

185 Musers, really? How many active and really reachable?

I wonder if she will mention XMPP or other standards.

I did not know DRaaS (Digital Recovery as a Service). But it seems just an empty marketing term.

Switching to French because the talk is in French

Luxchat4Pro – La messagerie instantanée souveraine pour les professionnels

#Luxchat est opéré par LU-CIX, le point d'échange.

Il utilise #Matrix (comme le #Tchap français, mais Luxchat est ouvert au public.) Chiffrement de bout-en-bout, serveur au Luxembourg.

I suggest you check whether the home site of each presenter’s company is still up while #cloudflare is down and only listen if it works…

I learn that insurance companies can pay the ransom. But it is typically the smallest expense in an attack.

@javerous @petaramesh Oui, j'ai failli intervenir à la table ronde aux #LuxembourgInternetDays https://mastodon.gougere.fr/@bortzmeyer/115569761763194290 sur ce thème. Aucune boite dont les données perso ont fuité n'a perdu un seul client. Le cours de l'action de Crowdstrike est revenu à sa valeur d'avant un an seulement après la panne. Etc. Il n'y a pas de feedback.

Le décideur rationnel a bien raison de ne pas s'en précoccuper.
