Quandl down?

I'm unable to import quandl data in the backtester.

The line of code that errors out:

from quantopian.pipeline.data.quandl import cboe_vix  

The error:
ImportError: No module named quandl

Well never mind, it seems to be working again. But any idea why this would happen? What if this happens for somebody live? Should we be encasing our data imports in try and except statements...?

Edit ***
It's acting up again.

Hey there - this problem should be fully resolved now. Really sorry about the confusion and frustration on your end!

Thanks, Ian! No worries.

Sorry if this is documented elsewhere (all I saw was documentation on mid-day failures), but what happens if code errors out prior to market open in live trading? Will it continue attempting to initialize before market open? Or does it get one try each day, and if that attempt fails nothing happens until the next trading day?

Hi Andrew,

Your question about errors in live trading is a good one. The answer is "it depends".

If your algorithm hits an error prior to market open due to a server issue or database error like the error you noticed today, if we can solve the issue prior to market open, we will try to start the algorithm again. However, if we cannot solve the issue before the market opens, we will not try again. In this situation (not able to start the algo by market open), we try to email authors of affected algorithms and notify them that their algo will not be trading that day. The author can of course decide to manually stop and restart the algo if they want it to restart mid-day.

Does this make sense?
