Okay. So as I've pointed out in a couple threads I've posted on, I think I have an idea what the deal is? But I don't have many data points, and so I could use your help -- hopefully if my theory is right we can make the tech support folks take notice?

Here is what you can do to help:

1. Run a traceroute to "neolobby02.ffxiv.com" -- if you don't know how to do this:
  • Windows: Accessories > Command Prompt > tracert neolobby02.ffxiv.com
  • Mac: Terminal > traceroute neolobby02.ffxiv.com
  • Linux: If you're a linux user I can't imagine you don't know how to traceroute!
2. Check the output for a line mentioning "tiscali.NET" -- if you're an RCN customer like me, it's probably the first hop after you stop getting RCN hops.

3. If you find a "tiscali.NET" hop in your trace, AND you're getting the lag spikes/rubberbanding/90k DCs, can you post here affirming that fact?

Now, caveat: I'm not a network tech. I don't REALLY know that this is what's going on. But every time I connect to the NA/EU data center, I check my route and ping, while watching the game, and every time I lag out/DC, it's because my connection stopped at the tiscali.NET hop.

Anyhow, scientific method, right? Gather data, draw conclusions. Hopefully if we find something useful we can take that to tech support and get this resolved soon.
