We stopped updating this site on June 30, 2024. From now on, information on Educational Campus-wide Computing System (ECCS) will be provided at utelecon The Portal Site of Information Systems @ UTokyo.
The Changed e-mail address and password for ECCS Cloud e-mail through UTokyo Account User's Menu (utacm.adm.u-tokyo.ac.jp) usually takes time for the data to be updated to Google system.
The updating process starts at every hour on the hour, and after that it takes about 30sec to reflect to Google system. If server is busy, it may takes about 5min.
