Heroku is built on top of Amazon EC2.  We're using the east coast  
datacenter.  The connectivity is usually pretty good - Amazon does a  
great job there.  At most, it adds 100-250ms latency to asia, but that  
shouldn't make things really slow.

We have on the todo list to support additional "regions" - today I  
believe amazon only has one in Europe, but are working to add one in  
asia somewhere.  If EC2 is being filtered, this won't help though.

Good luck,
Oren
