I tried 4 times to submit a site and all I got was this reply:

The following errors were found in your submission:

We were unable to access your web page. Please double-check your URL.
Please correct and resubmit your information below.

And I have done many of these so I know I am doing it right and our site is up.... so did anyone else have problems with them today?

Are you still having this problem? if so, at which point in the submission process?
