Stranded on a deserted island is bit radical, but I recommend going to a place with no internet connection for a week or so. I though I had a long reading problem. Turns out, I have an internet problem.
some 40 years ago in the Netherlands we had no TV broadcast at night because people should be in bed.
I wonder if an ISP could forge a product like noon till 7 (or even 4am till 9am) when few people use bandwidth. Perhaps combined with a very slow connection the rest of the day.
