Since last night, the test solutions in the draft are in waiting whenever we tried to execute them. So, we are unable to test the solutions and test inputs. Requesting to fix the issue.
Thanks for reporting this. There was an issue with one of our storage servers. Unfortunately the alerts were fired when we were all offline. The issue was fixed today, early afternoon.
Please let me know if you continue to face any issue.
I am sorry for any inconvenience.
It was solved really quickly. Thanks.
