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.

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.

Power Failure Tonight, Downtime

I take the somewhat unusual approach, of hosting my site, and this Blog, on a personal computer which I name ‘Phoenix’. This means that the availability of this Blog is only as good, as that of the PC in question, and its presence on the Internet.

Tonight there was a power failure at 18h30, for which reason this Blog also went off-line.

The actual power-failure only lasted 10 minutes. But there was never any obvious reason why it would have happened in the first place, for which I reason I do not know whether to expect more power-failures. For the same reason, I chose to wait until 20h15 tonight, to reboot ‘Phoenix’, at which time my site and Blog also became available again.

Because it was never clear as to why the power failed this time, there is the ongoing possibility, that there could be more power failures in the overnight hours. I apologize for any inconvenience to my readers.
