The organizers of all previous CIS tournaments were also confident...
I strongly recommend that all future organizers, when choosing a location, bring N laptops and set up a mass streaming session (of any content) to check the picture quality.
Of course, but for some reason, it's happening during the May holidays, and the internet, which was tested and stable, suddenly disappears. For example, in Volgograd, this was due to the fact that no one could reboot the equipment for two days, and the signal was already excellent.
