Free reachability checks across Russia: a domain, IP, subnet or ASN — one report.
What it is
The service matches registries and CDN overlaps, runs DNS, TLS and TCP measurements from Russian networks and puts it all into one clear report.
Why
To understand where and why a resource does not open: registries, DNS, connectivity and data from different regions and networks.
Who it is for
Website and service owners, infrastructure operators — anyone dealing with "it does not open".

Questions
How much does it cost?
Nothing: checks are free and the project accepts voluntary support.
Why "no data" instead of "reachable"?
A missing answer proves nothing — the service does not pass a guess off as a result.
How does it relate to SecureSysteamGhost?
The SSG panel checks customer domains through TSPU on a schedule and shows the result in place.
