How to check site availability from Russia
Availability is not the same as the absence of a block. A site may fail to open from Russia because of hosting, a geo-firewall, overload or a regional operator — with no registry record at all. Check from several Russian nodes: Moscow (multiple ISPs) and St. Petersburg. The Moscow vs St. Petersburg difference is different operators and routes. Cross-reference the availability result with EAIS registry status — only together do they yield a diagnosis.
Below: details, example, related guides, FAQ. This is diagnostic guidance for resource owners using the public EAIS registry — not circumvention advice.

Details
- Availability and blocking are different axes. “Unreachable from Russia” can mean a block, or an infrastructure problem. Do not conclude from a single signal.
- A single-node check is misleading: you need several points and operators. enterno.io /rkn uses check-host.net nodes in Moscow (×2) and St. Petersburg.
- Moscow and St. Petersburg are served by different operators with different DPI/filtering points. A difference in availability between the cities is a normal diagnostic signal.
- Free public nodes cover 3 points in Russia (Moscow ×2, St. Petersburg). More cities require RIPE Atlas (credits) or your own VPS — a roadmap item, not a requirement for basic diagnosis.
- Cross-reference: “reachable from RU nodes + no registry record” = fine; “unreachable + in registry” = blocked; “unreachable + clean registry” = check the CDN IP and your own side.
Example
# RU-node availability + registry status (together)
https://enterno.io/en/rkn
# Basic response check (from any network — for comparison)
curl -sS -o /dev/null -w 'http=%{http_code} time=%{time_total}s\n' https://example.com/
# Resolve via a Russian DNS (Yandex)
dig +short @77.88.8.8 example.com A
# Decision matrix:
# reachable from RU + not in registry → ok
# unreachable + in registry → blocked (see delisting procedure)
# unreachable + clean registry → CDN IP / geo-firewall on your sideRelated

Why check for RKN blocking?
Roskomnadzor maintains a registry of blocked sites. If your domain or IP is in the registry, Russian users won't be able to access the site. The check shows status and reason.
RKN Registry
Direct query to the prohibited sites registry — domain, URL, or IP.
RKN DNS Check
Simulate queries via provider DNS (Rostelecom, MTS, SkyDNS).
IP Blocking
Check if your hosting IP address or subnet is in the registry.
Reason and Number
If blocked, show decision number, date, and legal basis.

Frequently Asked Questions
How does availability differ from a block?
A block is a record in the EAIS registry plus enforced filtering by the operator. Unavailability is the observed fact “the site won’t open”, which has a dozen causes besides a block. The diagnosis comes from cross-referencing both signals.
Why is checking from one point not enough?
Operators filter differently and with a lag, and routes vary by city. A single node gives a false “reachable/unreachable”. You need several RU nodes plus a registry cross-check.
Can I check from a specific city other than Moscow and St. Petersburg?
Free public nodes are limited to three points (Moscow ×2, St. Petersburg). For other cities people use RIPE Atlas or their own VPS in the target networks — that is advanced diagnosis; the existing nodes are enough for a basic check.
