High Wind-Gusts For now

I host this blog on my home-PC. This means that the blog’s availability is only as good as that of my PC. I do not advise everybody to do it this way; this is just how I do it.

Well right now we are experiencing 80 km/H wind-gusts in Montreal, that are expected to continue throughout the night. Of course, since I also live in a suburb, this could bring about a power-failure. Therefore, within the next few days, this site and blog could go down.

If this happens, I encourage my readers to be patient with me. There would be nothing I could do about it.

Power Cut Planned.

I take the unusual approach, of Hosting my blog and my site, on my PC at home. What this means, is that the visibility of this blog is only as good as the reliable uptime of the same, home-computer. This is different from what most people would  do, which would be, to go through a professional hosting service.

One benefit of doing it my way, is that I get to tinker and reconfigure my server as I wish, while small-scale hosting arrangements usually require, that the client / author accept the PHP libraries that his hosting service provides, the database which his hosting service provides, etc..

An unfortunate fact which has been brought to my attention, by way of a courtesy letter, is that my power utility will need to replace a batch of power meters, of some minor glitch in the way they do or don’t work. We have power meters that report our consumption wirelessly to the utility, and if there is a malfunction, it’s within their jurisdiction to replace meters.

But, at some point in the next few days, a professional working for the utility will actually have to remove the present meter, and insert a replacement-meter. Which implies that briefly, my power will need to be cut.

This should not take long, and I thank my readers for their patience.

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.

Future Downtime

I host my Web-site, and therefore also my blog, on my own server at home – i.e. using my home connection to make this site visible to readers.

This makes me susceptible to power-failures, which would cause this site to be unavailable temporarily.

I’m also a customer of the power utility named “Hydro-Quebec”.

Hydro-Quebec has just given me a courtesy call, according to which they have scheduled work to be performed on the power-lines in my neighborhood, due to which a planned power-cut is to take place, on Tuesday, July 18, 2017, “from 12h30 until 15h30″.

In anticipation of this power-cut, I will actually be shutting down my computers, to avoid any danger of file-system corruption. Therefore, my site will not be available around that time.

I apologize in advance, to any readers who may find this to be an inconvenience.
