Update: The new tracker will go live today. The box strategy will be suspended and the recovery time will be fixed. Please pay attention to the official notice.
To celebrate the launch of the new tracker, the station will be free for one day on August 2, 2019 (please note that since the tracker has a cache, the actual station exemption start time may be after 1 o'clock on August 2, 2019.)
