Basic Statistics on the Overview Page are blank

How do you see a list of all driver rankings?
Mine is also blank, it is an ongoing issue for some that they are working on. All your data is still on the servers and eventually will be restored.
It has helped me win some vRP in the Competitions though, by being "unranked" I've been able to get into the top 10 of the unranked players in the Premium Competitions and eligible for the random draw.
As @Majuh said, for Leaderboard times, you will need to check each Leaderboard.
