• Sertãonet makes a small São Paulo fibre footprint visible at IX.br

  In Sertãozinho, a household broadband choice is not an abstract technology purchase. It is a monthly decision about whether a local provider can keep a home office, a school video call, a WhatsApp storefront, a rural-service desk, or a small repair shop connected at a price that survives comparison with national cable and fibre brands. Sertãonet Internet sits in that local contest as a micro regional provider with its own autonomous system, a visible IPv4 and IPv6 allocation, fibre and radio plans on its public site, and evidence of presence at the São Paulo internet exchange. The economic question is not whether that visibility makes the company large. It does not. The question is whether network-resource visibility can help a small access provider defend margins, quality perception, and bargaining options in a city where fixed broadband is already dense, rivals advertise hundreds of megabits for mass-market prices, and customers can switch quickly when service feels ordinary.
