I don't know which part of the country is going through this issue of internet shut down but in my country here, I'm yet to hear such a thing. Well as you rightly stated it might not be entirely shutting down, it just a case of maintenance which I know it isn't a new thing because every now and then there's always this routine or scheduled maintainence exercise that needs to be done which will help give users effective and efficient internet connection at a very good speed. So if they will be gone for about 5-8 hours to maintain the internet then so be it, it better that way than a breakdown before them working on any of the problem. With the stage and era we are in now. I don't see any shutting down totally of the internet,such thought is non existent now.
