On October 30, updates were made to how metrics are calculated for the Vital Signs dashboards [1]. The result is an apparent jump up or down on some of the metrics starting October 30th. This is because we did not update the existing historical data. We are planning on recalculating all the historical data after more work is done on the backend over the next month.
Here are the changes on the metrics:
- Namespace Edits and Pages Created now include pages in all namespaces and pages that have been deleted. The plots for these metrics generally show a step up. On wikis where most of activity occurs on pages other than in namespace '0' (like Meta and Commons), you can see a dramatic difference in the data [2].
- We exclude bots in Rolling Active Editor, Rolling Surviving New Active Editor and Rolling Recurring Old Active Editor. The plots for these metrics show a small step down. This change is not as conspicuous as the previous one.
If you were relying on this data right now, and need it consistent across time, please speak up.
