Who says there are explanations? It's basically an accepted and unavoidable fact of life that you can't access certain foreign Internet services at times. It is what it is.
I mean I'm used to the United States where almost anything the government does the government has an answer for it (albeit probably not good answers). I guess in large part the free press sort of forces this.
So are you saying the government doesn't issue an official stance and that they just do it?
