Clients Web sites Dropped - Does this mean they're Banned?

[jb123]

Hello! Since this new dance we have had five our clients sites dropped from Google! Another words, when we search for the sites in the past search terms or if we enter the url in the search box nothing appears. Does this mean their sites have been banned and if so, how do we find out for sure and why it has been? In the past all of these Top 10 ranked web sites have gone through Google's Dance without disappearing so, why would it happen now. I very worried but I don't want to send my clients into a panic. Any advice on these dropped urls?

Thank you for your immediate help!

P.S. Does anyone know if we submit a NEW site during the dance will it get in now? How is the best way to do that?

looking at www2 or www3?

and have you been upto any tricks, and not just in the last month.

jb, are they heavily linked together or close to being duplicates? That would concern me, but if they're all on one server chances are there was some down-time at the wrong time.

Use the submit at Google for them, people have been advised to do that before. And if there's nothing dodgy suspected, you might try linking to one of them from a page that gets "fresh" crawls.
