dns11 and ns11 show old ip address

Hello everyone,

My **domain name** is : be-chris.de
I have the following problem / I would like to set up :

After my ip address has changed by the provider i updated the ip address via ovh api.
In the api the new ip address is shown, but the dns entries served by ns11 and dns11 answer withe the old ip address since 24 hours.

API
{
subDomain: ""
zone: "be-chris.de"
ttl: 60
id: 5266979340
target: "83.76.17.4"
fieldType: "A"
}

but dig shows
dig @ns11.ovh.net be-chris.de. ==>
;; ANSWER SECTION:
be-chris.de. 3600 IN A 188.63.136.195

How can i force the dns update ?
Thanks
Chris
