We are now in official mirror list of Ubuntu

[Shan Ting]

As we recover from the hardware failure, we have been re-added to the official mirror list of Ubuntu. You can verify the sync status of Ubuntu from official Ubuntu Mirror Status page(https://launchpad.net/ubuntu/+mirror/mirrors.zju.edu.cn-archive). If you find any problem using Ubuntu with ZJU Mirrors, please open an issue in Issue Tracker, we will follow up asap.

Sincerely,
VXST
