Regarding the current situation
We are pushing the servers to the limits but allowing in as many people in as possible. Current record 230k people connected at once
Maintenanace beginning of 4th September Japan time
We are progressing smoothly with our plans to install new worlds as well as the load testing of the contents finder. If everything goes along as planned, installation should be done by tomorrow and we will begin internal testing from Monday onwards.
Judging by our current progress and estimates, we will implement a long maintenance on 4th of September Japan time where we will bring live the new worlds and rebalance the contents finder.
We are are expecting a rush of people logging in once maintenance is over so we will be monitoring the situation and relaxing the restrictions as it balances out.
Regarding addition of free play time
We are considering including a further 7 free days of play to all currently active and dormant (legacy) FF14 accounts. We plan to begin adding these extra days once the maintenance is over. I will update the exact date and time of when the the extra days will be provided once we have finalised the plans.
