Do you think regional servers will help?
I was sad to see the news that regional datacenters would be used because of all of the complaints from the player base. Before i get to my opinion of this, i would like to present some facts.
My "lag" (latency) from my computer to Durandal server is 176-198ms. That is about .2 seconds. I live a third of the way around the world from Japan (flight from my city to tokyo is 7264 miles, the world has a circumference of 24901 miles.) You can not get much farther away without being in the middle of the atlantic ocean, so let's just say that i am close to as far from the servers as you can get without living in Greenland.
The complaints that i have heard and the "lag problems" (as some call them) that i have experienced are well beyond this latency, usually coming to a couple of seconds or more (ifrit eruptions.)
If the datacenter was in your city, you would AT BEST shave off about 1/5 of one second of latency. do you really think that this would help?
I would suggest that instead of we the player base complaining about where the servers are located (which is often just a crutch for inexperienced players), maybe we should look into our own ISP or ask SE about implementing countermeasures for the full latency to the user (including graphical lag, responsiveness to the user [looks to be under control for 2.0] and such).
I think that regional servers are a sad idea and will break up linkshells and unintentionally push us into national groups rather than having a global community. It will also make it so that no one on your server will have a "JP Button" and that will be sad.
What do you think? is less than half a second no matter where you are worth breaking up the global community?
