Smart devices constantly perform DNS lookups to reach cloud services, authentication systems, and update servers — even those that appear to work locally. When DNS becomes slow or unreliable, devices drop offline, automations fail, and apps report errors, all while Wi-Fi and internet connectivity look perfectly healthy. Consumer routers create a single point of failure by forwarding all DNS requests through one service. Practical improvements include using redundant public DNS providers, running local DNS resolvers like Pi-hole for visibility and reliability, and actively monitoring DNS response times and query failures before problems escalate. ## Full article daily.dev links to this article rather than hosting it.
