Unfortunately, today unexpectedly some errors occurred on the servers that we restarted before the round. We couldn't resolve them within 30 minutes. Half of the servers continue to work steadily.
I don't want to risk hosting the round. A round preparation includes too much collaboration between the authors, coordinator, and testers. I have made the decision to postpone the round so that we can hold it in the future with confidence that everything will be fine.
I apologize for the inconvenience. Today I will delve into what is happening and figure it out. There is no reason to think that something will not work for tomorrow's round.
We will announce the new date for Round 875 later.
Apologies again for the inconvenience, Mike
UPD: The round is rescheduled on May/28/2023 17:35 (Moscow time).
