A few weeks back a mentioned a hack that would allow you to see how many pages were in the supplemental. Google has fixed that hack. But thanks to this site http://oy-oy.eu/google/supplemental/?Ǭ† you can do this once again. This cool tool checks all the datacenters. You can even pay $50 and name a datacenter after yourself.

Thanks to SEO egghead for the heads up on this tool.
