You should have a host cache list of lots of servers and that will get you started if you wait till it finds one host (that will then give you 10 more). What lame *** client are you running that doesn't have a host cache? Better send a nasty message to that author!
You need to know how to do this because you can't always depend on these central servers.
While you are at it, think what you are going to do when the power and water get cut off at your house.
Damn, one little glitch and you all freak out.
