Due to heavy load and lots of submissions from over 200 students, Frontdesk has run out of disk space and hence cannot process or accept more submissions. The frontdesk maintainer has been alerted and will fix the problem as soon as possible.
The course staff will discuss and decide how this will affect late
days and make an announcement when a decision has been reached. In the
meantime (i.e. ASAP) if you ran into submission issues, you'll want to
email your submission zip to your TA.
