Server random dc and rollback is retarded

Last night i was in lab and got random dc just to found out that even if i have to do whole lab again all items i got from it dissapeared with dc. Today lag was unberable on lab run for some reason fps was fine but server started to go ekg mad and on last Izaro encounter lagged so much that even if i stand still my character somehow ended up in traps in all left area in room not to mention i stand all time when i cast not using cyclone or something like that.Later after that i got again random dc on atziri losing all loot ofc altogether with map, then again cupple hour after that same as upper one lost loot currency maps, and again 5 min ago while running map.This problem persist for 2 days now for me but other people in global encounter same lag spikes and rollback dc-s as me not to mention that perandus is again going wild on some encounters so ether freeze screen or got hudge lag spikes.Wonder if any one from staff are known of this problem and will it be fixed soon. Playing on EU server Amsterdam if it helps to look for it.

Thanks in advance.
