ISP Resolver Caching & Split-Tunnel Routing
Returning to the Canadian account access and telemetry hub confirms when regional gateways are operating normally, meaning most sign-in loops originate inside local browser or network settings. On Apple devices running macOS Sonoma or iOS 17+, iCloud Private Relay routes traffic through dual-hop relays that occasionally rotate exit IPs mid-handshake, causing session guards to drop newly issued tokens.
Residential routers on Rogers Ignite, Bell Fibe, and Telus PureFibre also cache DNS records aggressively. Flushing local browser site storage or switching to encrypted DNS over HTTPS eliminates stale redirect records without erasing saved passkeys across other websites.
