Routine Kernel Update Today, Downtime

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.

libc Updates today, Downtime

This computer is a Debian / Jessie (Linux) system. Just today, it mainly received an update to its ‘libc‘ libraries, that comprised 16 packages. These libraries are essential to the core of how every program works. Therefore, even though it is a Linux system, it needed a reboot.

The update seems to have gone smoothly, but because this computer is also my Web-server, my site and blog would have been offline from about 20h30 until 20h45.

It is also not feasible for me to display a Maintenance Mode page during such a time, because a Web-server would need to be running, in order actually to display a Maintenance Mode page.

I apologize for any inconvenience this 15-minute interval may have caused to my readers, but it was essential.

Also, because this was a full reboot of my host-machine, my ‘memcached‘ (server-side) caching daemon was restarted, for which reason the most-favorite postings retrieved by my readers will be a bit slow to fetch for some time.

Sorry again,

Dirk

 

Major Upgrade This Evening, Downtime

Both the Linux-laptop I name ‘Klystron’, and the server of this Web-site, this server being named ‘Phoenix’, received a major update this evening. On ‘Phoenix’, a total of 78 packages needed to be updated, including a Kernel-Update, and a Graphics-Driver Update. This collective update effectively converted both computers from Debian 8.7 to Debian 8.8 systems. And both updates appear to have succeeded, at first glance without breaking anything.

However, this was an update that required a reboot for ‘Phoenix’, even though this is my Web-server, and so my site was also down briefly, from approximately 20h40 until 20h50.

I am happy to say however, that ‘Phoenix’ had been running for 58 days straight, without requiring any reboot whatsoever until tonight.

Oh, but I must disappoint some of my readers with the fact that performing these updates also required I restart my ‘memcached‘ service, which means that pages or postings the readers like to visit most often will be a bit slower to fetch, until this server-side caching is replenished.

Routine Kernel-Update Today, Downtime

I take the unusual measure, of hosting my Web-site on my own server. Yet, from time to time, updates come to this same host-machine – which I name ‘Phoenix’ – and some of those updates require a reboot, even though it is a Linux computer. When I do this, my site temporarily becomes unavailable. In fact, even though my installation of ‘WordPress’ has a page, I am unable to display it in most cases, because that page still requires for a Web-server to be running, to display on your browser.

Just today, there was a Kernel Update pushed through the package manager, to Kernel version . And so I felt it was only reasonable to perform the reboot. Also, there were some more-minor updates to ‘‘, but those would not usually, by themselves, require a reboot.

Because the entire process ran smoothly and without notable incident, my site and blog were only offline from about 12h35 until 12h45.

I apologize for any inconvenience.

Also, because my ‘‘ daemon has been restarted, this blog will seem a bit sluggish for the next day or so.
