It's a common misconception that the WoW-US servers are all located in one place these days.

From WoWWiki: http://www.wowwiki.com/US_realm_list_by_datacenter

US realms are hosted for Blizzard in several datacenters across the United States. They are located in:

* Boston, Massachusetts
* Dallas, Texas
* Los Angeles, California
* Seattle, Washington

While new players often wish to choose a realm matching their own time zone, those realms may be actually be located far away from them. For example, some servers in Los Angeles have realms on US Eastern Time, and some servers in Boston have realms on US Pacific Time. Instead, players may first wish to pick a datacenter to which they have good internet connectivity.

which is most of the time har har. Malaysia boleh.
