UPD (kinda late, but still): admin has posted below. I think most of the issues have been resolved except for running on the IDE, but there may still be some.
Hey everyone! Currently, there are many posts reporting issues for the Lunchtime going on today. Of course, this is necessary, but creating many posts is a disorganized and hard-to-follow way to do this. So, please report all issues you’re having on this post, rather than creating new ones. Also, pinging @admin to see this thread.
Here are the other posts that have already been made:
Unable to access the chef code server during lunch time (addressed below)
Codechef server (addressed below)
There is a bug in div 2 (resolved)
July Lunch Time 2020 (resolved)
And also a few reports on the announcement:
I am not a codechef admin, and have no power to fix this. I just want to make it a bit easier on the admins.
