System Maintenance Today, Downtime

I take the somewhat unusual approach, Of hosting this Web-site, and therefore also my blog, on my personal computer at home. Therefore, any downtime of my home computer, also affects the visibility of the blog. And, as long as the actual Web-server is not online, I also cannot make it display a maintenance-mode page.

Just in recent days, I took the more-unusual step, of running the command:


root@Phoenix:/home/dirk# update-initramfs -u -k 3.18.0-14-generic


What was unusual about this, was the fact that this was not the command:


root@Phoenix:/home/dirk# update-initramfs -u -k 3.16.0-4-amd64


While it seemed nice for some time, to be running a kernel-version named ‘3.18.0-14-generic’, the mainstream version which a Debian / Jessie system is supposed to be running, is ‘3.16.0-4-amd64′. So, while the mainstream kernel had been receiving regular updates, I was running a kernel, which had not been receiving any updates, for years now. This helped reduce the number of reboots which I needed to carry out, due to frequent updates on the ‘3.16.0’ kernel.

But just because this was the first time in ages, that I had run the ‘update-initramfs’ command on the running kernel, I next needed to attempt a reboot, just to see whether the computer could still boot.

Therefore, readers would have experienced problems accessing my blog or site, from about 16h40 until about 17h10 today.

And No, My system Failed to Reboot.

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,



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.
