We are aware of the pre-dominant lag thats being experienced today in our AOTB Server. We are running some backend operations which is causing a high load on the server (and hence lag). This is not a player/server issue, they report perfectly stable.
Ways you could be experiencing this lag: Chat Lag,Block Delay, Mod Damage & Movement Delay
We are monitoring the situation and the servers will return to normal once the operation has been completed.
