Those trying to upload new businesses via the bulk upload spec are receiving errors. Those errors read:
Unable to connect to feed processing server Please try again in a few minutes.
Trying again in a few minutes or even days later did not help.
One person said this has been an issue for them for over a week.
Mike Blumenthal also reported this and no one has an ETA for a fix.
Update: This is now resolved as of December 6, 2010.
