There are a few threads in the Google Places Help forum with complaints that the bulk upload feature to add new businesses to Google Maps is not working.

Those trying to upload new businesses via the bulk upload spec are receiving errors. Those errors read:

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.
