MabiPro: The Authentic Old-School Mabinogi Experience

Hey, old time Mabi player (currently don't play at all - I quit a while ago)

I remember something along the lines of the actual Mabi server being on the west coast which in turn affected the latency of a player on the east cost (lagless-ness?)
Where is this server based?

For all intents & purposes, you can consider it located in New Jersey.
This is subject to change and could switch to New York and back occasionally.

Hopefully that answers your question.
