Server lag problem?

I'm on Behemoth, and it feels like I'm playing under 600-900ms ping all the time, outside of dungeons. Crafting skill takes 2-3 seconds before registering. People no longer walk, they teleport around like Nightcrawler from X-Men.

I have ping command setup to the server IP and it shows constant/stable 40ms or less. My ping to google.com also shows constant/stable 10ms or less.

So, am I the only one suffering this problem, could it be driver/hardware problem.. because it feels like latency issue... or is this server problem? It's most noticeable when in Ul'dah or Mor Dhona, and during day-time.. as the problem ceases after midnight.

Here's a thread with the same issue. All 129 pages of it.

It's not just you.

It just gotten worse recently, more specific, since the last maintenance. I've never felt the latency to be worse than mere 200-300ms, but now it's up to 700-900ms by feel.

Others have reported the same, and I have also noticed it. During Early Access, I barely noticed the lag (there was some, but not difficult to compensate for), and after each server maintenance/update it has slowly gotten worse, this last one being the worst. Not only general lag, but there will be lag-spikes and rubber-banding (everything but you freezing and then everything snaps into quick motion, catching up on what you missed server-side, and sometimes killing you with AoEs that you never saw).
