I was monitoring my website earlier, and there was a massive spike in the number of page views, up from around 200 to 3000, at midnight, so not a time you expect your website to be busy.
Strange. I didn’t notice any spikes like this in my apps when checking recent logs. One thing you may want to do is install 3rd party analytics (like Google Analytics) to serve as another source of statistics like page views. This would also reveal how these views are originating without much legwork (basic JavaScript snippet copy and pasted into your app’s Settings page -> SEO/metatags tab).
