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.
