I use the atypical methodology of hosting my Web-site on my own, private server at home, named ‘Phoenix’.
This evening a major Update needed to be done on this machine, involving 99 Linux packages, which nevertheless took place in a completely routine way. But, according to all common sense, this one required a reboot.
As a result, my site should really only have been inaccessible for the brief time interval from 20h15 until 20h20.
I nevertheless apologize for any inconvenience.
