https://exquisite.tube/videos/watch/90b409cd-d9b5-4d24-8009-fa700aeab304 When your DNS resolvers and internal authoritative name servers go down, everything goes down. We needed a setup where failover is automatic and consisted of several layers of redundancy - so we turned to BGP. This talk walks through our current production architecture, where Unbound serves as the resolver and ExaBGP orchestrates route withdrawals for fast failover. I'll share what we've learned setting this up and outline our plans to extend it further: possibly replacing ExaBGP with OpenBGPD for a more flexible BGP integration, and introducing multi-vendor DNS software to eliminate single-point-of-failure risk at the application layer in the case of a software bug. Along the way, I'll dig into the specific challenges we faced in parts of our network that are IPv6-only - in particular, getting DNS64 to work in a complex internal DNS landscape.
