According to the official site this one is postponed because of the current measures in Slovenia. They will find a new date.
Slovenia are currently testing the whole population to try get ahead of Covid-19. As far as I understand they are giving certificates to the ones testing negative, so they could enter stores and so on. It´s looks like massive testing is the strategy. I could see the postponed event go ahead with a new date with the strategy if they manage to get control over the cases. International Skaters would probably have to be tested when entering the country, and re-test before the competition before they start - and could participate if they have a negative test result.
