There is a power outage or a network failure, as I was playing on a pc, I always had a laptop next to it and a mobile Internet connected via a smartphone. Since I play on a smartphone, I have no problem with anything because in the absence of access to the fixed network, it switches immediately to the mobile one. Power grid failures happen, but rarely. If you have access to mobile Internet, you can protect yourself by playing on a smartphone or tablet, laptop and, if necessary, have a larger powerbank with which you can top up mobile devices, then disconnecting from the network is not a problem and you can finish the tournament. In Poland, in the region where I live in Silesia, which is heavily urbanized, breakdowns happen very rarely, usually after storms and interruptions of transmission lines, fixed-line internet also works stably and breaks due to failures are also not frequent, and the mobile network always remains very well developed .
