Analytics is stats.wikimedia.org actively maintained any more?

Less than before. I am the only maintainer of Wikistats 1 and since July I work 30 hours per month, on my own request.

Wikistats 2 is the path for the future. It does provide traffic reports [1], and highest level metrics on content, edits and editors [2]. The community wish list for migrating more detailed dump derived reports is still the point of reference [3], but migration to the new hadoop based infrastructure is of course to be weighed against other priorities, and there are many. I'll be working on further documenting Wikistats 1, use cases for migration, etc, as requested by the Analytics Team. So I may be on the critical path right now. Hope to start that early September.
