According to the 2023 Internet Segment Reliability Report, Brazil has remained as the most resilient country to global internet failures. This distinction places Brazil as the only South American nation among the top 10 globally, surpassing its regional counterpart Argentina, which holds the 19th position, with the United States ranking just ahead in 18th place.
Milton Kaoru Kashiwakura, an expert interviewed by SBT News, attributes Brazil’s resilience to its robust internet infrastructure, particularly the presence of major internet content providers like Google, Meta, Netflix, Amazon, and Microsoft. These companies host their servers in data centers within Brazil, ensuring that even if the connection through submarine cables to the rest of the world is disrupted, a significant portion of internet content remains accessible locally.
The ranking:
- Brazil
- Germany
- Netherlands
- Great Britain
- Ukraine
- Ireland
- Canada
- France
- Switzerland
- Poland

“In the case of damage to submarine cables in the Red Sea, only those communicating with relatives or conducting business in affected countries would notice any impact. The primary services and content used by our users are hosted in Brazil and the United States and remain unaffected,”
– Kashiwakura
Kashiwakura serves as the Director of Special Projects and Development at NIC.br (Brazilian Network Information Center), tasked with implementing decisions and projects for Brazil’s Internet Governance Committee (CGI.br), responsible for coordinating and integrating internet initiatives and services in Brazil.
He also emphasized that despite the country’s independence, the biggest challenge lies in the Northern region, which still faces broadband shortages when any of the routes serving Manaus encounter issues. The vast distances and high costs of serving this sparsely populated region have led to the adoption of satellite internet as an alternative.
How it was tested
The way internet reliability is measured involves looking at how many Autonomous Systems (ASes) in a region would lose connectivity with Tier-1 operators if one AS experiences network issues. This question is important because it shows the global impact of local network problems. Originally, it was assumed that ASes would have multiple upstream providers for fault tolerance, but many now rely on just one provider, leading to increased risks of outages.
To rate AS reliability, a model is applied annually. This model examines alternate paths to Tier-1 operators for every AS globally using an AS relationship model. It also assigns weights based on IP address distribution and analyzes potential outage impacts on other ASes and countries. This process helps identify which ASes have the most significant impact on regional internet reliability.
