Code:
$ telnet websocket.mtgox.com 80
Trying 69.64.54.38...
telnet: Unable to connect to remote host: Connection refused

Yep was down, found the reason, fixed the code and restarted it (division by zero when someone sent badly formatted draft-00 headers).
Hello, thanks for the API. Few questions/comments:
a) What exactly is the ticker? Why server broadcast so many packets without any changed data? I see few updates per second without any change...
b) Can you please post example of subscribe/unsubscribe command? It's not clear for me how to unsubscribe from ticker.
c) Can you include (official) server timestamps to the broadcasts? Client timestamps in trading platforms are hell... I'm sorry, I miss 'date' field

a) The ticker is the current stats about bitcoin. It's sent once each time it have a chance to be changed, which includes when orders are posted, removed or completed.
b) Here's an example:
Code:
{"op":"unsubscribe","channel":"xxx"}
Additionally each user has a "own" channel which streams informations about orders (new order, deleted order, etc) and trades only the user's trades).
Does a user's "own" channel include information about when BTC/USD funds post to his account?
Not at this point.
why are you using UUID's to name the channels rather than just something human readable like: "trades" ?
Because it was easier since I intend to use this system for many other sites, without having to do something to isolate users of a specific system. Also there are user-specific channels and many other stuff which makes use of uuid a bit easier (for me).
