The app has no visitors and I am the only user/tester. `Analytics` is now turned on, yet I am still the only user and visitor of the app. ## Questions 1. How do I investigate this sudden spike on resource usage that occurred on one particular day? 2. How do I prevent getting suspended, considering that I am over the limit without knowing why? Thank you.   Pauline P. Narvas (@pawlean) · 2026-04-02 Could you check your Edge Requests for suspicious user agents, IP addresses, or referrers? I recommend enabling Attack Challenge Mode just in case. Go to your project settings → Firewall → Bot Management → Enable Attack Challenge Mode. This is FREE and won’t count blocked requests against your usage. I recommend: * Set up [Spend Management](https://vercel.com/docs/spend-management) to prevent future surprises (even on Hobby) * Consider custom firewall rules to block specific bad actors you identify * Enable [Vercel’s Bot Protection](https://vercel.com/docs/bot-management) managed ruleset for ongoing protection
