Yes those are the only explanations I came up with as well, but none of that applies.
I have kept a log of all IPs I regularly connected from, and only a single one of those originated in another country - another European one.
Never lost a device (jinxed now) or bought or even temporarily used a second-hand one.
An ad or intrusion do seem to be the most likely culprits, but ads are blocked everywhere, and I believe my security hygiene to be pretty decent.
This has been going on for over a decade now. Due to the sporadic nature if these happenings, I'm almost starting to think there's some old (but still wrong) data stuck on some edge node somewhere - or perhaps someone at Google is actively teasing me for being so critical of the company :)
