Small battle, large battle, absolutely random situation, doesn't matter.
Gray Host since U50 just freezes screen of an active player for 1-3minutes after witch player find himself logged off and Cyro spot is also lost after logging back.
That means back to 1-2hour queue during primetime, so basically end of PvP for the day.
No client side network issue.
Before U50 classic game crash sometimes, but without loosing Cyro spot, but now it's server side forced logoff with always lost Cyro spot.
