Users and Streams interfaces randomly change status after going offline

Correct me If I’m wrong, but does that mean that there are multiple servers that handle responding to the same API calls and at a given time they can hold different data under the same parameters? Is it pure luck, what you get and when, because you never know if you’ve just recieved data from a server that holds updated data or not?

Perhabs it’s a result of me being a total newbie, but that seems to be a bit silly.
