It is not risk. If your relevant regulatory body decides that your reasons are not legitimate (and if you definitely are using them to prevent service degradation and don't keep them around forever, I don't see why they would) then they will tell you so you can alter it.

Companies hate building business models and practices around "Well, if the regulator's cool with it, then..." That's the very sound risk makes.
