I suggest using your own DNS server and some other external DNS service rather than OVH if you want to get around it. I don't use a secondary service since if DNS is offline the rest of my server normally is as well, so it's pointless anyway.

Actually i configure my DNS for 1 day ttl on my dedicated servers , its quite common when you handle thousands of domains , not to overload the system traffic and cpu with un needed DNS requests.

thie combined with the IP failover system ( which allows to move the IP to another server ) , gives you the time do switch the ip in case of a migration without lossing your records.

makes sense.

Is changing the TTL then also possible?
There is no guarantee in the order of servers used. The client could ask OVH servers before your own. The solution is to run your own dns service only. If you have multiple servers you can assign 2 (or more) of them to resolve your domain.

I'm afraid that at the moment is not possible. A TTL of 1 day is quite common and it's to avoid extra load in our servers.
In that sense, a TTL of 300 seconds would e impossible, but I can request something lower to be implemented to our head offices. But honestly, it's quite an accepted value so I don't think it would be changed.

Alternatively, if you use your own DNS on your dedicated servers, you could of course set the TTL freely.

I have a feature request for dns managemend in manager.

Currently the TTL for dns records on OVHs dns server is 1 full day
is there a possebility for implementing a TTL input box?
lets say 300 seconds up to 1 full day?
