steveb, thanks for posting your findings on this topic.

After ten days the old Supplemental pages should show their new "PageHasMoved" caches. If you search for that text restricted to your domain, those pages will show in the results, BUT they will still ALSO continue to show for searches for the text on the ancient Supplemental caches.

When the pages show for their "PageHasMoved" text, are they still listed as supplemental, or do they appear to be part of the normal index at this point?

I also have to wonder if those 15% datacenters have anything to do with something Matt Cutts noted on his blog last week:

I have heard some reports of people having issues with doing a 301 ... but we may be due to replace the code that handles that in the next couple months or so.
