Website Availability in Russia

Wondering whether a website is down for everyone or just unreachable from Russia? The answer usually hides in the physical layer of the internet. Russia 🇷🇺 connects to the global network through 13 submarine cable systems that come ashore at 28 landing stations, and its national domain zone is .ru. Every request from a user in Russia to a foreign server, and every request from abroad to a site hosted in Russia, physically travels over these systems or their terrestrial backhaul.

This page summarizes what our measurement network knows about internet connectivity in Russia: which cables serve the country, how its leading internet providers are performing, and what can make a website appear offline for users there while it works everywhere else.

Current connectivity status in Russia

As of our latest hourly measurement cycle, the national internet signal of Russia is operating normally (BGP visibility and active probing dip: 0.2% against the 24-hour baseline). National-level signals catch large events; an individual website can still be unreachable for local reasons, which is what the availability checker above is for.

Connectivity for most users in Russia is provided by a small group of networks:

If a website fails to load only for customers of one of these providers, the problem is almost always local: DNS resolution inside that network, ISP-level filtering, or a routing issue, rather than the website itself being down.

Submarine cables that connect Russia to the internet

The following systems land in Russia. Cable length is a rough proxy for how much of the world a system reaches: long trunks connect continents, short ones link neighbors. Our monitors registered 1 latency anomalies on cables serving Russia in the last 30 days.

Plus 1 more systems, mostly regional links. Live health data for every cable is available on the linked pages.

How resilient is Russia to cable failures?

With 13 cable systems across 28 landing stations, Russia has a well diversified set of routes. A single cable fault is usually absorbed by the remaining systems, although latency to some regions can temporarily increase. Repairs at sea typically take one to several weeks, because a specialized cable ship has to locate the fault, lift the cable and splice it on deck.

Why a website may not load in Russia

When a site works in other countries but fails in Russia, the usual suspects are, in order of likelihood: a DNS problem inside a local ISP, a content delivery network misrouting users in Russia to an unhealthy edge node, a routing or peering issue between local networks and the site's host, and finally a submarine cable incident affecting the whole region.

There is one more factor specific to Russia: national-level filtering. Our DNS measurements classify blocking in Russia as moderate, with about 19% of tested resources returning manipulated or blocked responses. If a site falls into a filtered category, it will appear permanently down for most users in the country while remaining fully reachable elsewhere.
