Turning off the internet isn't impossible per-se, it's just very difficult without disastrous effects on the local economy. I don't know how developed Uganda is, but I can tell you for sure that if the internet is blocked in the US or any major European country, everything stops, including real-life things such as card payments and even airport timetable signs (interesting fact: most of the UK ones run a Chrome instance displaying a webpage hosted by a Romanian company). Even if access to national services is unaffected, those services themselves depend on various SaaSes that would be affected by the international blocking.
