DNS checks from Indonesia query your domain's authoritative nameservers from the Google LLC node in Jakarta and record the response and query time. Google's infrastructure in Jakarta means that managed DNS providers using Google Cloud's anycast infrastructure will show very low query times from this node. For authoritative DNS providers with a Singapore anycast node, query times will be around 15 ms. Self-hosted authoritative DNS without a Southeast Asian presence will show query times of 60–80 ms or more as queries route to Hong Kong or beyond.

GeoDNS validation from Indonesia is relevant for operators differentiating ASEAN traffic from global traffic. AS396982 from Jakarta should be geolocated to Indonesia by current GeoIP databases. If a GeoDNS policy targets Indonesia or Southeast Asia and the DNS check from this node returns a global or US IP rather than the regional one, the GeoIP coverage for Google Cloud Jakarta IP ranges is missing from the policy, or the authoritative server for the Asia-South-East region is not responding correctly.

Indonesia's PANDI (Pengelola Nama Domain Indonesia) operates the .id country-code TLD and maintains nameserver infrastructure within Indonesia. For .id domains, DNS checks from Jakarta will show low authoritative query times since PANDI has local infrastructure. For global TLDs (.com, .net, .org), the authoritative DNS chain is the same as for any other country — the DNS check from this node exercises that chain from an Indonesian vantage point, which is useful for confirming that your zone is correctly served globally including from the Asia-Pacific region.

Indonesia is the fourth largest internet market in the world by number of users, with over 200 million active internet users. The country is an archipelago of over 17,000 islands, which creates unusual infrastructure challenges — submarine cables connect the major islands (Java, Sumatra, Kalimantan, Sulawesi), but terrestrial fibre density outside Java is significantly lower than in comparable population-size markets. Java, and specifically Jakarta, concentrates the overwhelming majority of the country's internet exchange capacity and international connectivity.

IIX (Indonesia Internet Exchange) in Jakarta is the main national IX, operated by APJII (the Indonesian ISP Association). OpenIXP and JK-IX operate as independent neutral exchanges in Jakarta alongside IIX, giving networks peering options without being dependent on a single fabric. Despite three exchanges being present, a significant share of intra-Indonesian traffic still exits via Singapore for inter-ISP routing — a known inefficiency in the market that APJII has been working to reduce by expanding IIX participation and capacity.

Our probe node in Indonesia runs on AS396982 (Google LLC) in Jakarta. Google Cloud has a region in Jakarta (asia-southeast2), making Indonesia one of the few Southeast Asian markets outside Singapore with a direct Google Cloud presence. The AS396982 node benefits from Google's private backbone for inter-region traffic. Reference RTTs from this node: Jakarta to Singapore ~15 ms, to Hong Kong ~45 ms, to Sydney ~60 ms, to Tokyo ~80 ms, to Mumbai ~70 ms, to Frankfurt ~185 ms, to Los Angeles ~190 ms.

The dominant Indonesian carriers are Telkom Indonesia (AS17451, the incumbent) and its subsidiary Telkomsel, Indosat Ooredoo (AS4761), and XL Axiata (AS24203). Telkom operates the national backbone (NUSANTARA-21) connecting the main islands via domestic submarine cable. Most international capacity exits via Telkom's cable landing stations, which connect to Singapore — Jakarta to Singapore is only 15 ms, and the Singapore-based IX ecosystem (Equinix SG) effectively serves as the international peering layer for Indonesian carriers.

Testing from Jakarta is relevant for operators serving the Indonesian internet market. With 200+ million users and a rapidly expanding middle class driving e-commerce and streaming adoption, Indonesia is an important market for regional services. The 15 ms Jakarta-Singapore RTT means that Singapore-hosted services perform well for Indonesian users, but local Jakarta hosting (as with the Google Jakarta region) offers a further latency advantage, particularly for latency-sensitive applications like gaming, video calling, and financial transactions.
