Two entries from ther official Mediamax blog on 17 October 2007. You can't leave comments there, so leave them here:
We have resolved the upload processing issue mentioned in the previous post. The backlog has been processed and any new uploads will appear immediately. Thanks again for your patience.
We are currently experiencing processing issues. Uploaded files may take as long as 70 minutes to appear in user accounts. We'll post here again when the situation is resolved.
We apologize for any inconvenience. Thanks for your patience.
So how is uploading for you now?
