Question "Zone update frequency/latency", by Arthur Pierce P.

I want to be able to switch a CNAME back and forth a few times while troubleshooting an issue. I've changed its TTL to 5 minutes, but I haven't found any indication of how long I should expect it to take from the time I submit my edits to the webform, to when [abc].dns.gandi.net start serving updated DNS records.

If I update a record with TTL of 5 minutes now (:58 past the hour), when should I expect to see the newly record in DNS queries such as dig www.leftasanexercise.com @a.dns.gandi.net ?

Thanks, -arthur.
