Regarding Reports on Recent Connection Problems with the NA Data Center

I'm also in Arizona on Cox with this exact same issue. I started a thread which got moved to the "Separate Support Required" section and locked.

You might be being routed through a section of NTT's network located in Los Angeles which seems to be heavily congested. Judging by the Technical Support forum, along with Reddit posts this is an issue effect a great number of players who have to use this particular NTT hop. It's been an ongoing struggle.

Try running a Traceroute to FFXIV's lobby server.
tracert 209.2.229.9

Then check if you see any of NTT's hops located in Los Angeles
I.e. lsanca20.us.bb.gin.ntt.net

I've been running a ping to FFXIV when I got home today around 4:30PM PST and monitoring it. I get the occational packet loss, but not enough to impact gameplay. However sure enough, like clockwork, as soon as 7:30PM PST rolls around, the one particular Los Angeles NTT node becomes congested and the rubberbanding begins.

Pinging the node in question, ae-3.r01.lsanca20.us.bb.gin.ntt.net
10% packet loss


And pinging all the way to the FFXIV Lobby server
12% packet loss


Unfortunately, its been like this for me for over a month, and looks like something NTT has to fix (not Cox)
