What if a company told all its customers this:

"We only have the capability to record your activity on server X. Currently you are using server Y. Click here to be re-assigned servers."

In other words, if such a company got an warrant regarding a user, they would always handle that user on server X. Therefore, that user would be able to tell they were being monitored (to some % certainty) by refreshing their server assignment several times. If they were always assigned to server X, they could conclude that the company was probably trying to record their activity. A user couldn't be 100% certain because it would be possible that they were randomly assigned to X every time.
