Lithuania, Latvia and Estonia (in that order) will disconnect from grids in Königsberg (Kaliningrad), Belarus and Russia (in this order). After that the area will be working as isolated grid for 33h, after which the grids will be connected to synchronization link between Lithuania and Poland. Königsberg will remain a grid-island.
