How to Repair your LAG!

[Nuzio]

Most ISPs have given FFXIV the category of P2P software and will automatically reduce connections and put them in a lower queue. What that means to you is slow service and lag. Call your ISP and complain. This is a fact.

How do I know? Just called in for a friend (very not computer savvy friend) to Verizon since he has been having a lot of issues lately and after giving Verizon the specified information. The IP, traceroute, and so on; the tech replied with this IP (the one sending information from FFXIV servers) has been flagged for Peer-2-peer and has been placed in a lower priority queue. After talking with him he was able essentially set up something similar to port-forwards where as if the IP address is directed to the IP address of said friends router it will not get placed into the lower queue. Viola! No more lag.

SE can only request to ISPs to not give it that designation. To solve the problem you need to contact your ISP and get it fixed. This is a problem between you and your internet provider. Not FFXIV or SE.

Or for those of you who are ready to flame at SE, this isn't the first time this has happened for an online game. Blizzard went through this itself before it was removed from that category years ago.
