Hi there! Quick Stats is separate from Quantcast data, and we'll be getting Quick Stats fixed as soon as we're able.

Quantcast data is no longer public, unfortunately, because it includes proprietary business information. We know that some users were relying on it, and we're sorry for impact this change has on you. Hopefully Quick Stats will be back to full power soon. We're also looking into other methods for providing data to users in the future.

To help us out with that work, can you tell us more about what specific data you were watching, and how it helps you out? Thanks!
