Up until about 36 hours ago (since around noon MST on 11 Dec) everything has been working flawlessly for 3 weeks. As far as I know nothing changed, and I have verified that API keys and datafeed URLs are matched between FoxyCart and FoxyShop. This is in relation to the suethomasdvd.foxycart.com store. After that point yesterday, now every single transaction is getting a datafeed error:
DataFeed Failed: (23674347) 2012-12-12 14:57:33 No data returned for http://suethomasdvd.com/foxycart-datafeed-64214948bad4/
 connect() timed out!
I get the same result when I try to manually refeed. I've searched on similar threads and skimmed through the primer on errors. Kind of at a loss where to look next. What could have changed all the sudden that datafeed is failing on every transaction when it was working prior with dozens of transactions? What else should I check?
Thanks in advance!
