Facilitator question

I would like to know if the facilitator is only helping during the connection or if it is working also after the initial connection?
I was wondering if an overloaded facilitator server may cause lags in the game.

Thank you for your help.

As far as I know, it’s only used for the intial connection.

Well I am actually not so sure. Because sometimes when the facilitator server was under some attacks and was not working, if you were already in the game, you were disconnecting. Maybe I am wrong though.

Maybe someone else would be able to confirm?
