DNgap

DNgap is a lightweight tool for monitoring both domain and server availability from multiple global locations. Use it to verify reachability, inspect DNS responses, and confirm whether a site is accessible from specific countries — ideal for diagnosing regional blocks, CDN issues, or propagation delays.

Built for webmasters, CDN users, and site reliability engineers, DNgap delivers clear, actionable insights about global accessibility. Run checks from diverse locations to compare results, troubleshoot regional outages, and ensure your content is reachable where it matters most.
