I host my Web-site on my private computer at home, the one I name ‘Phoenix’. This is different from how most Web-sites today are hosted.
Phoenix received a kernel-update today by way of the package manager, which also required a routine reboot. As a result, my Web-site would have been inaccessible from about 20h05 to 20h15.
Also, I could not have posted a notification on my actual blog, indicating Maintenance Mode, because to output such a message would at least require that the server itself be running. Yet, there has been no real disruption to my Web-server, outlasting this reboot.
I apologize for any inconvenience.
