… we’ve just activated our own OCSP-resolver on our new arm64-servers.
This sounds a little bit unspectacular, but it’s a big milestone while replacing hard- and software within our environment as the old OCSP-resolver-software could not be ported to a recent debian and arm64-environment.
All other critical services (like Nameserver and CRL-Serving) were already moved successfully to our new power-saving machines (2 Raspberry Pi4) in the last weeks/months. OCSP needed some development and testing.
The virtual machines in the old environment are now stopped, within the next days the (power-consuming) sun3-server will then get it’s final shutdown and will be removed from CAcert-Rack during the next visit at the datacenter.
Our main website and signer-software will still be kept running on dedicated servers.
Today we switched the connection to our main website as a preparation for a “bigger” change. Unfortunately this (temporary) change is not IPv6-capable, so only IPv4 is working currently.
Over the weekend we plan to move www.cacert.org to another server for a more recent environment and add a second firewall to our rack. During this server-transition you may face some issues while using www.cacert.org, after the weekend the services should be normal again.
Early next week we’ll enable IPv6 again for our main website (maybe by using a new IPv6-Address, but that’s not yet decided).
All other services (like blog/wiki/bugs/…) should remain active as usual as there is currently no planned update.
Die FrOSCon (FRee and Open Source CONference) ist eine jährlich stattfindende Konferenz, die von der Hochschule Bonn-Rhein-Sieg und dem FrOSCon e.V. organisiert wird. Die FrOSCon bietet eine Vielzahl von Vorträgen und Workshops zu freier und Open Source Software. Die Veranstaltung findet seit 2006 regelmäßig Ende August statt. Eine große Bandbreite an Referenten verspricht zwei spannende Tage. Die Organisation wird ausschließlich von Freiwilligen übernommen.
Selbstverständlich ist auch CAcert bei der Froscon 2022 mit dabei. Wenn du während einiger Zeit mithilfst, zusammen mit unserem Event-Team den CAcert-Stand zu betreuen, bekommst du natürlich eine Aussteller-Badge und damit auch Zugang zum VIP-Bereich. Bitte melde dich bei email@example.com für eine Teilnahme.
Update: Nameserver-transition is currently finished, new DNSSEC-records are set and active. KSK and ZSK were replaced by CSK.
In the ongoing process to update hard- and software we’re moving our main domain cacert.org to another master-nameserver-machine (with different nameserver-software) within our rack …
As we’re using DNSSEC to secure our domains, we need to update KSK and ZSK-keys for our domains during this progress, too.
Therefore you may face some DNSSEC-errors or issues in resolving cacert.org-domains within the next days, but this should resolve itself within some hours/days.
As soon as the transition of the nameserver-move is finished, I’ll update this post.
Todo: Give ns1.cacert.org the “old” nameserver-address again (after next hardware-change onsite) so secondary-nameserver ns3.cacert.org can get back to work. ns3 is currently not listed at our registrar, so not active for CAcert-Domains.
Geoff Huston from APNIC talked at the RIPE 84 about certificate revocation as a “sanction”. He concludes that the certificate infrastructure is not working, and instead suggests DNS is the answer. You can put keys in the DNS and use TTL to control the caching lag of the information.
How do you see it? What conclusions should we draw from this at CAcert? Write your comment below!
Sie wurden bekannt, indem sie sorglosen Umgang mit Sicherheit ausnutzten: Mit geleakten E-Mails und gehackten russischen Servern sorgte die Internetaktivisten-Gruppe Anonymous auch jüngst wieder für Schlagzeilen. Doch wer steckt hinter dem Kollektiv? Hier teilen die Investigativ-Journalisten der NZZ ihre Erkenntnisse über Ursprünge, Funktionsweisen und Tätigkeiten von Anonymous mit uns.
Moving www.cacert.org to new hardware was not successful due to some firewall settings, so we decided to keep the old server active.
During the next days/weeks we’ll change some firewall settings remotely so short downtimes may apply before we try to activate the new server during the next visit in some weeks.
During the next visit at the datacenter on Friday we’re doing some hardware-changes within our rack, especially for our main website www.cacert.org.
As a preparation we will disable most of the services on www.cacert.org on Tuesday evening. The site will be fully operational again after the new server is up and running (most likely during Friday morning).
All other subdomains like blog/wiki/… will only have a short outage while we install a new firewall.

Roberto Cirillo has been CEO of Swiss Post for just under two years. Before that, he was a McKinsey consultant, CEO of the British hospital group Optegra and head of the activities of the service company Sodexo in France. Cirillo took up his post with the aim of stopping the downward trend. In the past five years, the Post’s turnover has fallen by around CHF 1 milliard. The volume of letters is decreasing rapidly, the post offices are less and less frequented.
In an interview with the NZZ, he said: “Today, we make more than 90% of our turnover in the logistics sector with business customers. Especially in e-commerce and goods logistics. Of the CHF 3 milliard we plan to invest in the next four years, the majority will go into logistics and communication services. The reason why the Post was created over 170 years ago was not to transport letters. It was the secrecy of letters. It was about transmitting information securely, reliably and trustworthily. That’s what we want to do more of in the digital world as well.” (22.02.2021)
