You may have noticed some instability with composr.app. This screenshot should sum it up:

The composr.app website is getting a LOT of traffic (unfortunately, it's from bots). The site on its own can handle it. However, the statistics addon cannot.

All of this traffic is resulting in massive amounts of data having to be processed by the statistics addon. It can't handle that in its current state.

I am working hard on a solution. Unfortunately, it involves a lot of complex database/SQL and heavy optimisation to how we previously handled statistics in Composr.

Until this fix is implemented, the site will periodically throw Bad Gateway errors. Just try again in 5-10 minutes.

I apologize for the inconvenience this is causing.
