HTTP checks from Singapore send a full GET request to your URL and record the status code, response time, and whether the response completed. The check includes DNS resolution, TCP connection, TLS handshake if applicable, and time to first byte. Singapore's connectivity to major CDN providers is strong — Cloudflare, Akamai, and Fastly all maintain edge nodes in Singapore, so cached content on those platforms should respond in under 20 ms from this node.

For origin servers outside Singapore, the HTTP response time will include full round-trip latency to wherever the origin sits. An origin in Frankfurt will add around 170 ms of network overhead before a single byte is returned. If your HTTP check from Singapore is slow, compare the RTT from the ping check against the HTTP response time to determine how much of the delay is network versus application processing. A slow TTFB on all nodes simultaneously points to the origin server rather than the network.

Singapore is the right HTTP test location for validating CDN coverage across Southeast Asia. If you have a CDN configured but your HTTP check from Singapore is hitting a distant PoP (visible from a high response time inconsistent with local RTT expectations), your CDN may not have Singapore in its edge network or the DNS-based steering is sending Singapore traffic elsewhere. Compare results from the Singapore node with nodes in Hong Kong and Japan to identify where the CDN edge selection is going wrong.

Singapore is the primary internet hub for Southeast Asia. Almost every submarine cable system serving the region either lands directly in Singapore or transits through it. SEA-ME-WE 3, SEA-ME-WE 4, SEA-ME-WE 5, APG, AAG, and SEAX-1 are among the systems with cable landing stations on the island. This concentration of cable infrastructure, combined with political neutrality and strong rule of law, has made Singapore the de facto interconnection point for traffic flowing between Asia, the Middle East, and Europe.

The Equinix SG1–SG5 campus in Singapore functions as the main carrier hotel and IX hub. Equinix Singapore hosts the SGIX peering fabric alongside its own Equinix Internet Exchange fabric. DE-CIX also operates a neutral exchange here, giving networks a third independent peering option. The density of networks collocated in this one campus means that most intra-regional traffic — between Singapore, Malaysia, Indonesia, Thailand, and the Philippines — crosses through Equinix without needing to exit the building.

Our probe node in Singapore runs on AS30058 (FDCservers). FDCservers is a US-based colocation and hosting provider with a Singapore point of presence. The node sits inside the Singapore market connected to local transit and peering, which means test results reflect realistic hosting network conditions rather than a direct telco backbone. Typical Singapore-to-Hong Kong RTT is around 30 ms; Singapore-to-Tokyo is around 65–70 ms; Singapore-to-Sydney is around 85 ms; Singapore-to-Frankfurt is around 170 ms.

Domestic network infrastructure in Singapore is highly developed for a city-state of its size. Singtel (AS7473), StarHub (AS4657), and M1 (AS9534) are the three main local carriers. Each maintains direct peering at the Equinix campus and provides transit services to smaller ISPs and hosting providers. Because Singapore is geographically compact, latency between any two points on the island is negligible — inter-carrier variation is driven by peering policy rather than physical distance.

Singapore's position matters for tests directed at Southeast Asian users. A server with sub-20 ms response times from the Singapore node is well-placed for the ASEAN market. Tests from Singapore to targets in Indonesia (Jakarta ~15 ms), Malaysia (Kuala Lumpur ~15 ms), and Thailand (Bangkok ~35 ms) provide a practical gauge of how regional content delivery is performing. If you serve users across the region, Singapore is the single most representative test vantage point available.
