is there anything new in this matters ?
icelandic domains cannot be assigned to a nameserver that has longer ttl than 24 hours, would like to have my domains controlled from digitalocean...
As of January '17, we've updated the control panel to allow for customization of TTLs on DNS records. We're making updates to the API to allow for TTL customization soon as well to keep consistency.
Here is the link to go directly to your domains to begin changing values: https://cloud.digitalocean.com/networking/domains
