Power Failure Today, Downtime

I take the somewhat unusual approach, of hosting both my site and this blog, on a PC at home. I’m not saying that everybody should do this; this is only how I do it.

What this implies is that the accessibility of my site is only as good, as the WAN connection of my personal Internet service, as well as the quality with which my PC can be kept running.

Today, my home experienced a brief power failure, from approximately 9h00 until approximately 9h10. Therefore, my server went down. Yet, because I did not get back home until noon to reset things, the site remained off-line until about 12h15. I apologize for any inconvenience to my readers.

As it happens, there have been relatively few power failures to my home, this Summer. On a typical Summer, there would have been more of them.

Kernel Update Today, Downtime

I take the unusual approach of hosting my site and blog, on my PC at home. This means that if my computer, which I name ‘Phoenix’, has any down-time, so does my blog.

This afternoon, ‘Phoenix’ received a routine kernel update, that seemed to go well. But because even a Linux computer needs a reboot after a kernel update, this site was down briefly, from 12h55 until about 13h15.

On the same note I should mention that yesterday, March 27, we had a power-failure from about 16h00 until 17h45. For that reason as well, my site and blog could not have been on-line.

I apologize for any inconvenience to my readers.

Power Failure, Downtime.

I take the unusual approach of hosting my Web-site and my blog, on my PC at home. I’m not suggesting that everybody do it this way. This is just how I do it. But the unfortunate consequence of that is, that my site and blog are only visible to the Internet, as long as my PC is up and running, and as long as my own Internet connection is stable.

This morning (March 15, 2019), while I was away, there was a power failure which literally lasted from 11h05 until 11h10 – according to my own log files. This means that the power in my home was out for maximally 5 minutes.

But, I only came back from my daily activities around 17h00. Therefore, with nobody at home to reboot my computer, the blog was offline for the duration, until 17h15.

I apologize for any inconvenience to my readers.

Power Failure Last Afternoon, Downtime

I take the unusual approach, of hosting my Web-site, and therefore also this blog, on one of my PCs at home, which I name ‘Phoenix’. What this means is that the visibility of this site and blog is only as good, as the availability of this PC.

Unfortunately, we had a power failure yesterday afternoon from about 14h55, that lasted until about 0h00 this morning. It’s unusual even for Montreal, for the power to be out for so long.

Because I was sleeping when the power came back on, I did not reboot ‘Phoenix’ until about 3h15 this morning, from which point on this site and blog were available again.

I apologize for any inconvenience to my readers.


I suppose that I could make a wild guess, as to why the power was out for so long, last night. At 15h00, the temperature outside was still 31⁰C, and we were having a severe thunderstorm. Any thunderstorm will have as side-effect, to overload the power-grid, in parts of the world like Montreal, where much of the distribution wires – that carry 14.4kV – are above-ground. This is because, every time a lightning bolt strikes the actual power line, this causes a brief brownout, which will usually not be enough to cause my computers to crash, but which will cause scores of air-conditioner compressor-motors to stall, simultaneously.

The combination of a severe overload, with outside temperatures of 31⁰C, which had not subsided yet, may have caused one of the main transformers in the transformer stations to fail. If that did happen, I’m guessing that the main problem of our power-utility would have been, to find a replacement for one like that quickly. The next problem would have been, actually to install the new transformer as a replacement for the old, blown one, quickly.

All in all I’m happy, that my computers – and this site – are Up again.

(Update 08/30/2018, 13h45 : )

I have written in another part of my blog, that when I am inside and there is inclement weather, I tend not to notice strong winds that are outside at all. Well after setting foot outside today, I compared my power failure with power failures that other people had, also yesterday. The picture I got was, there were numerous power failures, not one, and different times at which each person’s power was restored again. What this means is that not all the power failures, can have been caused, by one transformer blowing.
