Reachability Test
Understanding Our Testing Methodology
How It Works
The reachability checker performs a simple connectivity test from your browser to the target endpoint. It uses the Fetch API with no-cors mode to verify if a connection can be established.
This test runs entirely in your browser - no data passes through our servers. The result reflects your ISP's direct peering relationship with the target network.
Limitations
- Tests only verify basic connectivity, not speed or bandwidth
- Results depend on your current network and ISP
- Timeout is set to 5 seconds
- Some endpoints may require authentication
Note: Reachability does not guarantee content availability or legality. Always verify the status of external resources independently.
