I would search for someone who has a good connection to South East Asia. I'm saying that, because it might be helpful if for some reason you can not find a California based host, which meets your requirements (even I think you will find a lot which has good connectivity to Asia).

Give RapidXen/Nerios a look, was only with them for just over a month (was reviewing inexpensive VPS) but they were solid during that time. They do allow IRC with approval so just make sure you ask and their connectivity was pretty good out of Fremont.
