5 minutes downtime max if a switch needs to be done.
5 minutes is perfectly acceptable IMHO

= infra TTL standards are 60 minutes for service CNAMEs and 30 minutes for HA= CNAMES. The TTL is 600 here (which is 10 minutes, not 5) because I lowered= it on 1/14 in anticipation of a machine failover, it was previously 2 hour= s.
