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.

Power failure tonight, downtime.

This evening, Montreal experienced a forecast, severe thunderstorm. But what could not be forecast with certainty, was whether the power would fail, in my exact neighborhood. In fact, it did.

I take the somewhat unusual approach, of hosting my Web-site, and therefore also this blog, on my PC at home. The availability of this blog can therefore not be any better, than the availability of my PC, to the Internet. Therefore, this site and blog were briefly offline, from about 19h00 until 20h00. I apologize for any inconvenience to my readers.

Freezing Rain This Evening, Power Failure, Downtime.

I take the unusual measure of hosting my site, and therefore also this blog, on the home computer I name ‘Phoenix’, rather than on a professional Web-hosting service, the latter of which is what most people would use.

This has as unfortunate side-effect, that the visibility of my site is only about as good, as the up-time of the home-PC in question. Therefore, if there is a power-failure, the site will go offline. Even though one of the plug-ins I have installed on my WordPress platform is, to display a Maintenance Mode Page if I so choose, the visibility of such a maintenance-mode page would still depend on the software running, that is my Apache Web-server, as well as on this computer being connected to the WAN – In other words, such a maintenance-mode page will not be visible during an actual power failure, only if I decide to tinker with my blog, and if the server itself is still up while I’m doing so.

Later this afternoon (on 1/23/2018), we were experiencing sheets of freezing rain, and so predictably, the power went out around 17h40. But, just as Hydro-Quebec had predicted, they were able to restore power to my home, by 20h30 the same evening. Gosh knows what had gone wrong, but the utility was able to repair it very quickly, given the circumstances.

And so until about 20h50, this blog and site would not have been visible. I apologize for any inconvenience to potential readers.

(Edit 1/24/2018 : )

As it happens, my power failed again, around 22h40 the same evening, but only for about 5 minutes. However, this time, I did not restart the computer immediately after the second power-failure, instead deciding to wait until 6h50 this morning to do so. So again, the blog was offline until 6h50 this morning.
