Update #1:
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.
Original note:
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.
