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.
