Nope, there seems to be an issue. Even amiquote has stopped working. I tried the api call and the link as well, it won't fetch any data. Only Nifty and CNXPHARMA have downloaded manually. Its ditto for other stock exchanges worldwide. I managed to download MSFT once then it went blan kafter that. I wonder whats going on. In fact if you chekc #googlefinance on twitter, people are complaining.
