I host this site on a Debian / Jessie (Linux) computer, which I name ‘Phoenix’. Through the package manager, it receives routine kernel updates, and today was a day on which it received one.
Even on a Linux computer, a kernel update generally requires a reboot, which I carried out.
But, because This computer is also my Web-server, and the host to my blog, that means that for a few minutes my site and blog were offline – i.e., unavailable to readers. This was happening from approximately 19h45 until 19h55.
I apologize for any inconvenience.
For what it’s worth, I consider this to have been one of the least-troublesome reboots, that I’ve had to carry out over the years.
