- diolpah 15y agoSort of. Our site instances are shared-nothing peers, so there's no primary/secondary. Users resolve the closest host to them ( anycast geoIP )by default, but if one of the hosts goes unavailable, the DNS entry for that host is removed by our scripts.
- nodesocket 15y agoCool, who's your DNS provider who does the anycast geoIP?
- diolpah 15y agoZerigo, cool little startup in Colorado that got acquired earlier this year: http://www.zerigo.com/managed-dns http://www.zerigo.com/managed-dns Their API offers full control over everything, which is good because the way you set up geodns records is ridiculous - scripting it out is the best way to handle it.
