in Japanese and Korean.  But coordinating the sysadmin people in 
both places was too hard, so they moved everything back to one 
place in Florida (in September 2006).

sooner or later somebody will come with a suggestion to distribute 
facilities based on geography.  The people who run the servers had 
better fix any problems before this happens.  It's like the mine
