2. Is there a replacement for stats.grok.se planned or already available? A reliable substitute would be great, and it would be nice if we could either replace the existing on-wiki "page view statistics" link or add a supplemental link to the new resource.

Apologizes if this information was already published and I missed it.

Yes there is, a group of students from Sweden are working on the first attempt. If that doesn't succeed, others including our team have plans to help.
