An extensive upgrade to the machine which hosts this Web-server, in which 106 packages were brought up to their new version, took place between 20h25 and 20h45 tonight. Hence, the site would have been unavailable during that time, and because the Web-server itself was offline, it was not possible to display a Maintenance Mode screen, belonging to this blog.
The upgrade took place uneventfully, not breaking anything apparent so far, and leaving the computer fully functional.
