We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
Also look at the DNT and GCP headers (https://globalprivacycontrol.org/), and see if we can implement support for them. Document our use in tut_markup if we do.

Other stuff will be moved out too over time, until eventually this issue no longer exists.
