Hey guys,
I'm wondering what people use for naming conventions around their failover DNS records. We have our various SaaS applications under apps.xyzdomain.com. We have put in a failover server in Wellington that replicates every few minutes. If there ever is a problem at the main server the TTL update would take too long to just change its IP to the Wellington server so I'm thinking a seperate record to give to our customers. maybe something like:

backup.apps.xyzdomain.com

Anyone got ideas here?
