i want to make a gui that adds a Value in ban list of the play who is banned and i want it to save for every server that is up. i want to do that whilest playing the game so if there is a exploiter in the server and if i ban him in that server he cant join another server. how can i do that. the only part i am stuff at is that how would i save the Value for each server that i up. because i only know datastore that saves stuff on that server. please help.
i dont know how to explain that even further but if you dont understand it i will try my best to reexplain it. this is not a request you dont have to make the script FOR ME you can just link me to roblox wiki page that contains info about the thing i am asking i would really appreciate that.
Thank You.

DataStore doesn't save information only on a single server. You can get the information from another server instance as well. You will want to use 'UpdateAsync', if there is a chance for the data to be written to by multiple servers at once. Note also that 'GetAsync' returns a cached value, meaning another server will not be able to get the changes as soon as another server saves the information.
HttpService might be an alternative way to do this, but it would require you to have an external webserver.
ok ty for the help.
