Just a week back i wrote about GlobalPandora, a nice service that allows you to access Pandora outside US. At the time of writing that piece i thought that it may not last long, and today they are down.
They have put a message on home page saying that Pandora blocked all the US IP addresses globalpandora is using. If you are looking for some online radio like Padora you may checkout other options like Jango, Meemix, Songza, Fairtilizer among others.
Update: It’s back again, but showing some technical errors. [Thanks Simon for the tip]
