You can still use your facebook login. As long as it is unsupported, it will provide you with an informative message like:
"Facebook login does not work yet for the new server. Click here to login with email and password instead".
So, it is safe to use your preferred login all the way. Once it is reinstated, it will work.
Do note that propagation is a tricky issue and it is relative to ISPs too. So at one time it might work but at another it may not. At all cases, the game will provide the solution to login.
