Due to a power outage at the University of Tokyo Kashiwa II Campus that occurred at approximately 8:57 PM on October 25, 2023 (Wednesday), all virtual machines were forcibly stopped. After conducting a system check, we have resumed our services as of 10:30 AM on October 26, 2023 (Thursday).
To resume using mdx, you need to reboot your VMs from the User Portal. User Portal(ユーザポータル)＞ Virtual Machine(仮想マシン)＞ACTION button＞Power(電源)＞Power On(起動)

ユーザポータル＞仮想マシン＞ACTIONボタン＞電源＞起動

We sincerely apologize for any inconvenience this may have caused to all of our users.
If you encounter any issues or problems during the reboot process, please do not hesitate to contact us at mdx-help [AT] mdx.jp
