  • Apple's N1 chip boosts iPhone 17 Wi-Fi performance, Ookla finds
    November 19, 2025, 4:46 AM EST. Ookla's Speedtest Intelligence results show Apple's N1 networking chip - integrating Wi-Fi 7, Bluetooth 6 and Thread radios - delivering a real-world boost for the iPhone 17 family over the iPhone 16 Broadcom modem. While on paper the N1 matches the Broadcom spec, in practice it yields up to 40% faster median download and upload speeds globally, with 10th-percentile gains up to 60% in tougher conditions. In North America, the iPhone 17 outperformed flagship Androids for Wi-Fi downloads, delivering a median of about 416.14 Mbps and a 90th-percentile of 976.39 Mbps. Note the N1 doesn't fully exploit 320 MHz channels yet, but it offers more consistent performance as Wi-Fi 7 routers proliferate.
  • AWS outage exposes internet's reliance on a handful of providers, experts warn
    November 19, 2025, 4:42 AM EST. An AWS outage disrupted apps and websites worldwide, highlighting how the internet relies on a small number of providers. The glitch hit Snapchat, Roblox, Signal, Duolingo and Amazon-owned services including the main retail site and Ring, with more than 2,000 companies affected and 8.1 million user reports. While most services recovered within hours, some faced lingering issues as AWS limited requests to aid recovery. UK impacts included Lloyds, Halifax, Bank of Scotland and HMRC access problems; Ring users reported doorbell outages. Experts warn this dependence on cloud computing firms creates systemic risk, urging diversification of infrastructure. Think tanks and academics argue the crisis threatens critical infrastructure and democratic discourse, emphasizing the need for resilient, multi-provider strategies beyond the US tech giants.
