I am sad to see that you have so slow internet. Is the speed that low in general in your country? At the same time, 7hrs without electricity, it sucks... I hope you are ok now.
I am one of his countrymates and I guess he is okay with that. Usually, electricity does not shut down for that long in the winter season. But, sometimes they cut off the electricity for some maintenance. But, if we talk about seasons except for winter, it's pretty common to survive 10 hours without electricity. If you talk about slow internet, it's below average compared to the rest of the world.
Most internet users use 5mbps speed unless they need special speed for some special work like streaming or uploading content. That's why we hate online installers. We people always try to download the full package of any software.
BTW, I have downloaded Bitcoin Core's latest version and started downloading the block.
