Since August 2024, Azure Container Registry has a system of name reservation, to prevent re-use of subdomain name for a time after deletion. My question is how long is that time ?
How long must I wait to recreate the ACR in another tenant ?

Hi BLIGNY Stephane,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here
Based on your query After you delete an Azure Container Registry (ACR), the name is reserved for a period of time, but the exact duration isn't mentioned in the documentation. Generally, it’s around 30 days, but it’s not confirmed. We’ll update you as soon as we receive more information on this. During this time, only the original Azure AD tenant that created the registry can reuse the name. Other tenants won’t be able to use it until the cooldown period is over.
