Ping from our Santiago node (AS396982, Google LLC) sends ICMP echo requests and records round-trip time. Baseline RTTs from Santiago: to São Paulo ~48–58 ms, to Buenos Aires ~18–25 ms, to Miami ~107–118 ms, to Los Angeles ~120–132 ms, to New York ~138–152 ms, to Frankfurt ~230–250 ms, to London ~235–255 ms, to Tokyo ~185–210 ms. Google's backbone reduces these figures compared to standard Chilean ISP transit — a residential user on Entel or Claro typically sees 10–20 ms more to US destinations.

Chile is South America's westernmost connected country, which creates an interesting asymmetry: Santiago is closer to Los Angeles via Pacific cable than to Miami via the Caribbean, but most South American international cable infrastructure historically routed through Miami. Google's backbone routing from Santiago does not necessarily follow the historical Miami-centric path — it may route via Los Angeles or direct trans-Pacific depending on the destination, which can produce RTT differences from what older latency maps predict.

ICMP handling on South American carrier paths can vary. Some cable landing station routers on the Pacific Coast route do not return ICMP TTL-exceeded messages, producing asterisk gaps in MTR traces without representing real loss. A clean result at the destination alongside an MTR with intermediate asterisks is normal behaviour on these paths. Elevated ping RTT compared to TCP check times on the same destination indicates ICMP deprioritization rather than genuine path degradation.

Chile is the most connected country in South America by most measurements — fiber penetration, average bandwidth, and IX maturity. Santiago hosts two significant internet exchanges: NAP Chile and PIT Chile. NAP Chile (Neutral Access Point Chile) operates the primary peering fabric used by major ISPs, CDNs, and content networks. PIT Chile (Punto de Intercambio de Tráfico) provides a complementary peering point. Together, these two exchanges give Santiago a domestic traffic anchoring capability that reduces the need for Chilean ISPs to route local traffic through Miami or New York.

International connectivity from Chile exits primarily via submarine cables running up the Pacific coast toward the United States. The South American-1 (SAm-1) and PCCS cables carry the bulk of Chile's international capacity. The primary international landing station is in Valparaíso. Santiago to Miami typically runs 105–115 ms. Santiago to Los Angeles on Pacific cable runs approximately 118–130 ms. Santiago to São Paulo sits around 48–58 ms. Santiago to New York is approximately 135–150 ms. These figures reflect Chile's geographic position at the southwestern tip of South America — closer to the US West Coast than to Europe via any submarine cable route.

The Chilean ISP market is served by Entel Chile (AS7418), Claro Chile (AS14259), Movistar Chile / Telefónica (AS7418 / AS22047), VTR (AS22047), and GTD (AS11664) among others. Antel and Telmex subsidiaries also operate in the market. The domestic backbone in Santiago is well-developed, and most Chilean carrier infrastructure concentrates in Santiago rather than distributing across the country's geographically elongated territory. Our probe node runs on Google LLC infrastructure in Santiago (AS396982).

Google Cloud's presence in Santiago (AS396982) reflects Chile's status as the main South American cloud market outside Brazil. Google operates a South America West region (Quilicura, outside Santiago) that serves Chilean and regional Latin American cloud workloads. AS396982 uses Google's global backbone for international transit, giving it better-than-average peering to most destinations compared to what a standard Chilean ISP on Entel or Claro transit would see.

Our Santiago node provides a test location inside Chile's primary carrier environment with access to Google's well-peered network. Results from this node reflect how Chilean-hosted cloud infrastructure performs — useful for diagnosing whether a service is accessible from South America's most connected country, and what latency Chilean users or Chilean-hosted workloads experience toward European, US, or Asian targets.
