Don't let a CDN outage break your site silently

Most uptime monitors only ping your server. But modern websites depend on dozens of external resources - CDNs, analytics, fonts, scripts. When Cloudflare goes down, your homepage looks fine in your monitoring dashboard, but your users see a broken page.

Modern sites depend on external resources — CDNs, scripts, fonts, widgets. When one of them has issues, your site breaks. Your server is fine. Your monitoring shows green. Remember recent CDN outages? Sites went down not because of their servers, but because of a dependency. Most uptime tools just check if your server responds. upsonar.io parses your page and verifies all external resources are actually loading. Free tier available. Feedback welcome!
