Internet paths can change without applications changing
The route your traffic takes across the internet is renegotiated continuously by people you have no relationship with.
Nothing in your application changed, and today your data is crossing different networks in different countries from yesterday. It is a reason encryption in transit is not optional and a reason that assumptions about where data physically travels are usually unfounded.
