Just for a bit of comparison... I'm in the UK and don't drive. It is a 10-min walk to a big Tesco superstore, which is really convenient. It is on my commute too (which I also walk, Uber if its raining heavily).
My first thought was that they’d accidentally broken their BGP announcements, cutting themselves off. I don’t know enough about this topic though: are you saying there’s evidence they just stopped announcing their networks for no real reason, or is this graph a symptom of someone being something else being wrong, as opposed to being the root fault?

I have been using a vertical mouse for a long time now, and it is very comfortable for me. But it does take some getting used to, when I watch others trying to use my computer they always struggle with it. Interestingly as well as being more comfortable to use, I find that it improves my pointing accuracy, feels like fewer unnecessary movements.
