Round 195 will be the last one! Now scoreboard is green again, so good luck and hack em all (not jury system :d)!
Sorry everybody for the 1 hour total jury downtime. We’ll post the analysis of the event during the next week. I hope the last hour will be fun and productive for all the teams who haven’t left us yet. Thank you all for participation and great performance! Good luck!
Extend the event for the downtime period (1h)?

[email protected]:~/$ cat announcement.txtTwo years have passed as the world is wearing medical masks. The influx of covid waves will be the envy of any coast, and there are so many strains of the virus that you can assemble a platinum collection of the Greek alphabet. There was some hope for collective immunity a year ago, but so far only collective stupidity has won. Or maybe we can produce a new megavaccine?
[email protected]:~/$ cat announcement_ru.txtДва года как мир облачён в медицинские маски. Наплыву ковид-волн позавидует любое побережье, а штаммов вируса стало столько, что из них можно собрать платиновую коллекцию греческого алфавита. Ещё год назад была хоть какая-то надежда на коллективный иммунитет, но пока что побеждает только коллективная тупость. А может… Мы сможем произвести новую сверхвакцину?
Эксперименты с вакцинацией начнём 6 февраля в 13:00 по Москве, а в 21:00 узнаем, кто добьётся наилучшего результата.
