How eero mesh WiFi routers connect to the cloud

What this post added

This post details how eero uses Cloudflare as a 'cloud canary' to test internet availability from their devices. They store a small file in Amazon S3, protected by Cloudflare, to serve as a secondary internet check. This allows eero devices to continuously verify internet access without relying on third-party sites, preserving user privacy and providing an out-of-band, highly available, and low-cost method. Cloudflare's CDN serves this file from the edge, minimizing S3 costs.
