Everything that game_maker said and to add some context i lived in Mauritius and we often get maintenance ISP for undersea connection and also maintenance from CloudFlare(we get re routed to EU servers) so any website that using cloudflare either is slow or just doesnt load.
Data centres cloud servers are implemented mostly in well developped countries so am either not eligible(like nvidia cloud, playsation now etc…) or having restricted features because am too far.
For power outages, this happen often as well that why i have 2 UPS, one for pc and one for monitor+modem. 
I used multiple version of UE because i have different project version, especially cpp project where new version sometime affect my code. All my game dev friends also used different version, so when i have to test thier cpp project, i need the same version.
