Reporting Issues Resulting from the North American Data Center Relocation

[tacbox]

Type of Issue/Feedback: Dramatic ability delay in instances compared to on the striking dummy. My play is smooth on a striking dummy, but as soon as I enter an instance, the same input from me results in "hanging" of the abilities (not executing even though nothing else is happening with the character). The abilities eventually execute, but the character visibly stands there doing nothing for noticeably long periods of time. This occurs primarily during rapid input sequences (i.e., using multiple off-GCD abilities between GCD actions, or under the buff "Rapid Fire"). This results in the same series of actions taking approximately 20% longer. Latency to the server is a constant ~95 in instance or in the overworld, so the problem is not latency related. No changes to frame rate rule out a graphical problem. Literally the only difference is that I'm in an instance.
Name of your Internet Service Provider (ISP): Spectrum / Time Warner
State/Country: New York, USA
Date/Time: The ability lag occurs at all times, but only in instances. This began when the new servers came online, and has persisted.
World Name: Gilgamesh
Frequency: Every instance, every time.
Traceroute records with tunneling service active

As a quick side note, it makes me depressed to think that I can't play my favorite classes (MCH and BRD) at the level I'm used to. These classes both frequently require rapid input sequences, which is exactly when the problems I'm describing crop up. I've got no inherent problem with my new latency to server, but the fact that my experience decays so dramatically in instanced content means that, for all practical purposes, I can no longer competitively play my preferred jobs. I feel like something must be wrong with the instance servers, as many others have told me that their problems also exacerbate in instanced content. I'm feeling my excitement for Stormblood slowly drifting away...
