Website Availability in Poland
Submarine cables, ISP health and blocking risks that decide whether a website loads in Poland. Checked against live measurement data.
Wondering whether a website is down for everyone or just unreachable from Poland? The answer usually hides in the physical layer of the internet. Poland 🇵🇱 connects to the global network through 1 submarine cable systems that come ashore at 1 landing stations, and its national domain zone is .pl. Every request from a user in Poland to a foreign server, and every request from abroad to a site hosted in Poland, physically travels over these systems or their terrestrial backhaul.
This page summarizes what our measurement network knows about internet connectivity in Poland: 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 Poland
As of our latest hourly measurement cycle, the national internet signal of Poland is operating normally (BGP visibility and active probing dip: 0.1% 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 Poland is provided by a small group of networks:
| Provider | ASN | Share of users | Status |
|---|---|---|---|
| TPNET - Orange Polska Spolka Akcyjna | AS5617 | 24.3% | No recent anomaly |
| P4NET - P4NET | AS39603 | 11% | No recent anomaly |
| TMPL - T-Mobile Polska S.A. | AS12912 | 10.8% | No recent anomaly |
| PLUSNET - Polkomtel Sp. z o.o. | AS8374 | 9.5% | No recent anomaly |
| AS9141 - P4 Sp. z o.o. | AS9141 | 7.9% | No recent anomaly |
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 Poland to the internet
The following systems land in Poland. 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 no significant latency anomalies on these systems in the last 30 days.
| Cable system | Length | In service since |
|---|---|---|
| Baltica | 437 km | 1997 |
How resilient is Poland to cable failures?
With 1 cable systems across 1 landing stations, Poland has a highly concentrated topology that depends on very few systems. A single cable incident can severely degrade or even cut international connectivity. 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 Poland
When a site works in other countries but fails in Poland, the usual suspects are, in order of likelihood: a DNS problem inside a local ISP, a content delivery network misrouting users in Poland 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.
Our DNS measurements have not flagged systematic national filtering in Poland, although individual ISPs and corporate networks can still block specific resources.

Frequently asked questions
How do I check if a website is down in Poland?
Enter the URL into the free Global Availability Checker on this site. It compares measurement data from 80+ countries, including probes relevant to Poland, and shows in seconds whether the site is down everywhere or only unreachable from specific regions.
How many submarine cables connect Poland?
Poland is served by 1 submarine cable systems landing at 1 coastal stations. The longest systems are Baltica.
Why does a website work in other countries but not in Poland?
The most common causes are DNS failures inside a local ISP, CDN edge problems, routing issues between Poland and the hosting network, national filtering, and submarine cable faults. Testing the URL from multiple countries immediately narrows down which one it is.
Who are the largest internet providers in Poland?
The leading networks by user share are TPNET - Orange Polska Spolka Akcyjna, P4NET - P4NET, TMPL - T-Mobile Polska S.A.. Together they carry the majority of consumer traffic, so a problem inside any of them affects a large share of users in Poland.
Can a single cable failure disconnect Poland?
Yes, the risk is real: connectivity depends on very few systems, and one incident can cause severe degradation.
Does Poland block websites?
We have not detected systematic national filtering in Poland, but individual ISPs and corporate networks can still block specific sites.
