But doesn't Israel also not follow a typical work week? Eg. No commits on Friday afternoon?
…What I would really want is some input from Microsoft. I don't know what they can reveal, but I believe they must have quite a bit more data, than us. Even speaking about times, well, he must have been using Github more than to just commit stuff. And I'd imagine they have some logs. Also, it's very fair to assume than he was using VPN all the time, but it's also fair to assume that he wouldn't accidentally slip like that, revealing his real time zone in 9 commits. So, yeah, for sure there are people who have waay more data than me, and probably know how to use it properly better than me too. Not sure they will be willing to share, though.
I think I saw somewhere a claim that somebody confirmed he used a VPN, I'm can't recall how they did that.
I have a relative with mental health problems who lives on the street, and he sometimes writes me from public libraries -- kind of luckily for family members who are concerned about him, the webmail service he uses still includes that info in headers. So I usually know which public library he writes from.
