I have this in my logs:

A remnant from a cloud integration that has been deleted on your hub. That’s a Google IP address - did you have a Nest integration or something else Google-related?
I've not deleted an app for weeks, I won't have a backup that far back. I'll watch for if it happens again. It's not a sign something is trying to hack?
