I don't have the feeling that google finance is live and kicking. I think it's one of those product that will disappear soon. There are lots of broken feeds like:
I actually went to google finance where I could get live price feed when yahoo and my bloomberg terminal had 15min delays. Now even yahoo has live feeds too.

I reported some but they did nothing about it.
