Any puclibly viewable links for serverfiles are unranked. Ranked status can only be given if the server provider is licensed by DICE/EA. The licence is very expensive(and only given to "trusted" providers, I believe), so only the hosting companies tend to have ranked status.
Swapping a ranked server to unranked is actually as simple as setting a variable from 1 to 0 in the settings, for anyone who happens to run a ranked server and wants to try FS.
