The first day: Every node to the server starting from the fifth to last started lagging massively
Second day: The second node on the NTT network after leaving my own ISP network lagged out at least twice as bad as the first day and this hit me a lot harder than the first day lag.
Today: Same as two days ago.

I'll just be glad it doesn't flat out disconnect me like some other people. Whatever the case may be my connection to the server is being disrupted solely on the NTT network.
