I play on Alexander, a JP world, but I've never had problems with lag until about 2 weeks ago. At first it always happened around the same time each day, but it was negligible, it didn't affect my gameplay in any significant way, and I thought it was just because it was the peak activity time for the server because of all the JP players coming on. Then about 2 days ago, it got really bad. Lag spikes are spread across the entire day now, and sometimes everything just stops for 5-10 seconds, then the entire world goes into fast-forward.
