Website Availability in Singapore

Wondering whether a website is down for everyone or just unreachable from Singapore? The answer usually hides in the physical layer of the internet. Singapore 🇸🇬 connects to the global network through 44 submarine cable systems that come ashore at 8 landing stations, and its national domain zone is .sg. Every request from a user in Singapore to a foreign server, and every request from abroad to a site hosted in Singapore, physically travels over these systems or their terrestrial backhaul.

This page summarizes what our measurement network knows about internet connectivity in Singapore: 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 Singapore

As of our latest hourly measurement cycle, the national internet signal of Singapore 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 Singapore 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 Singapore to the internet

The following systems land in Singapore. 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 Singapore in the last 30 days.

Plus 32 more systems, mostly regional links. Live health data for every cable is available on the linked pages.

How resilient is Singapore to cable failures?

With 44 cable systems across 8 landing stations, Singapore 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 Singapore

When a site works in other countries but fails in Singapore, the usual suspects are, in order of likelihood: a DNS problem inside a local ISP, a content delivery network misrouting users in Singapore 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 Singapore, although individual ISPs and corporate networks can still block specific resources.

Neighbors on the same cables

These countries share submarine cable systems with Singapore, so a major cable incident can affect them together:
