Google Sheets

[Caversham]

I use Yahoo Finance for all of my data and my spreadsheet has been borked for the last week.  I've seen similar, flaky behavior before; so I was hoping this was a temporary issue, but it sounds like that might not be the case.

Is the issue with the ImportData function itself, or just ImportData from Yahoo Finance?  Basically, can we get data from another source? Google Finance is not an option, since its data is incomplete and often times just plain wrong.
