Speaking of F5 Big IP DNS devices, does anyone know of any auth DNS software solution for GSLB/health checking for DNS (I guess excluding Route 53 or other cloud/SaaS). Last I looked all I could find was the polaris-gslb addon for PowerDNS, but the GitHub for that has no activity in 8 years.
We've been using Polaris for the Loadbalancer.org GSLB for a few years now, and we've found it fast and stable. Its so simple its never needed any updates:
Although we did patch a dynamic health check a while back, which will be open source of course. But I'll get someone to check if we actually gave it back to the community or not...
