Level3.net drops 20-60% of packets - also they add 800-900ms static (400ms more per hop during prime time) per tracert test within 3 hops from Dallas -> Chicago -> Montreal (SE NA Server Clusters) and two hops between Montreal servers.

Tracert to both the World Server (test Ragnarok) and instance servers go through this Level3.net

FFXIV is routed via Level3 - my ISP (Verizon FiOs 100up50down) cannot help you once they hit the Level3.net nodes - it's outside their control.

Calling Level3 as an individual is a fruitless effort - they only speak with companies.


So there's nothing you can do but re-route yourself via a VPN for the time being.
