    Hi Sanchit Pruthi,
    The error indicates a temporary regional capacity restriction for Event Hubs Premium in North Europe. This is not related to your subscription quota or configuration. Premium namespaces require dedicated regional capacity, and new creations can be blocked when capacity is unavailable. Creating the namespace in a different region is the correct workaround, which is why it succeeded there.

    The error message "Namespace creation is restricted for this region (Code: NamespaceCreationIsRestricted)" indicates that there are limitations on creating new Event Hubs namespaces in the North Europe region. This can occur if the selected region has reached its capacity for new namespaces or if there are specific restrictions in place for that region.

    Since you mentioned that you created another Event Hub a day before, it's possible that your subscription has reached its quota for the number of namespaces allowed in that region. You may want to consider the following options:

    1. Select a Different Region: Try creating the Event Hub in another region where namespace creation is allowed.
    2. Check Quotas: Review your subscription's quota for Event Hubs namespaces and see if you can delete any unused namespaces.
    3. Contact Support: If you believe this is an error, contacting Azure support may provide clarity on the restrictions in place.

    It's important to ensure that the region you are trying to create the Event Hub in is not at capacity and that your subscription allows for additional namespaces.
