RefCheck.Radio sends UDP connection packets to each reflector registered on
DVRef.com for each mode, every ~30 min.
The timeout is 5 seconds per attempt; the service tries up to 4 times before listing
a reflector as unreachable. The page auto-refreshes to reflect the latest data.
Each reflector's IP is also checked against commercial hosting
provider ranges: ✓ indicates a commercial/hosting IP,
✗ indicates a home/residential IP.
Click any reflector ID in the table to view its outage history (up to 90 days). The Reliability Stats tab shows per-mode outage counts, most-unreliable reflectors, and the longest currently active outages.
This is not a "wall of shame" -- it is a resource for
both reflector users and operators to help make Digital Voice for Amateur Radio a Better
Place™. 💙
