Website Availability in Italy
Submarine cables, ISP health and blocking risks that decide whether a website loads in Italy. Checked against live measurement data.
Wondering whether a website is down for everyone or just unreachable from Italy? The answer usually hides in the physical layer of the internet. Italy 🇮🇹 connects to the global network through 39 submarine cable systems that come ashore at 55 landing stations, and its national domain zone is .it. Every request from a user in Italy to a foreign server, and every request from abroad to a site hosted in Italy, physically travels over these systems or their terrestrial backhaul.
This page summarizes what our measurement network knows about internet connectivity in Italy: 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 Italy
As of our latest hourly measurement cycle, the national internet signal of Italy is operating normally (BGP visibility and active probing dip: 0% 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 Italy is provided by a small group of networks:
| Provider | ASN | Share of users | Status |
|---|---|---|---|
| ASN-WINDTRE - WIND TRE S.P.A. | AS1267 | 19.3% | No recent anomaly |
| ASN-IBSNAZ - Telecom Italia S.p.A. | AS3269 | 18.8% | No recent anomaly |
| VODAFONE-IT-ASN - Fastweb SpA | AS30722 | 16.8% | No recent anomaly |
| TIF-AS - Scaleway SAS | AS29447 | 9.2% | No recent anomaly |
| FASTWEB - Fastweb SpA | AS12874 | 8.5% | 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 Italy to the internet
The following systems land in Italy. 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 5 latency anomalies on cables serving Italy in the last 30 days.
| Cable system | Length | In service since |
|---|---|---|
| 2Africa | 45,000 km | 2024 |
| Asia Africa Europe-1 (AAE-1) | 25,000 km | 2017 |
| SeaMeWe-4 | 20,000 km | 2005 |
| SeaMeWe-5 | 20,000 km | 2016 |
| IMEWE | 12,091 km | 2010 |
| India Europe Xpress (IEX) | 9,775 km | 2026 |
| Medusa Submarine Cable System | 8,760 km | 2026 |
| Middle East North Africa (MENA) Cable System/Gulf Bridge International | 8,000 km | 2014 |
| MedNautilus Submarine System | 7,000 km | 2001 |
| Blue | 5,055 km | 2023 |
| EMC West-1 | 3,639 km | 2027 |
| Jonah | 2,297 km | 2012 |
Plus 27 more systems, mostly regional links. Live health data for every cable is available on the linked pages.
How resilient is Italy to cable failures?
With 39 cable systems across 55 landing stations, Italy has one of the most redundant internet connections in the world. Traffic can reroute across many independent systems, so a single cable fault rarely affects end users. 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 Italy
When a site works in other countries but fails in Italy, the usual suspects are, in order of likelihood: a DNS problem inside a local ISP, a content delivery network misrouting users in Italy 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 Italy, although individual ISPs and corporate networks can still block specific resources.

Frequently asked questions
How do I check if a website is down in Italy?
Enter the URL into the free Global Availability Checker on this site. It compares measurement data from 80+ countries, including probes relevant to Italy, and shows in seconds whether the site is down everywhere or only unreachable from specific regions.
How many submarine cables connect Italy?
Italy is served by 39 submarine cable systems landing at 55 coastal stations. The longest systems are 2Africa, Asia Africa Europe-1 (AAE-1), SeaMeWe-4.
Why does a website work in other countries but not in Italy?
The most common causes are DNS failures inside a local ISP, CDN edge problems, routing issues between Italy 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 Italy?
The leading networks by user share are ASN-WINDTRE - WIND TRE S.P.A., ASN-IBSNAZ - Telecom Italia S.p.A., VODAFONE-IT-ASN - Fastweb SpA. Together they carry the majority of consumer traffic, so a problem inside any of them affects a large share of users in Italy.
Can a single cable failure disconnect Italy?
No. With 39 independent cable systems, traffic reroutes automatically around a single fault.
Does Italy block websites?
We have not detected systematic national filtering in Italy, but individual ISPs and corporate networks can still block specific sites.
