That is because there was a new patch last night and Survival Servers have been horribly delayed when updating their servers to the new patch. Basically your game is a newer version than the server and who knows when the update will be available to update our servers. This is the 3rd time we have had to wait 12-48 hours to update our servers after a game patch.
I am beginning to wonder if they are trying lose their Ark customers so they use the Ark servers for different games. I don't know of any other reason why this has become the new normal after updates.
