Azure App Service secure hostname

Hey Everyone, 

I see a new change in app service deployment related to the secure hostname. Is it now mandatory to have a secure hostname, because I don't see the option to toggle between the secure hostname and just the format for appservicename.azurewebsites.net ? I wasn't able to find any update notification to verify this change.

    Hi Hitarth,

    I noticed the same behavior recently. From what I've seen, Microsoft appears to be moving toward Secure Hostnames by default as part of its secure-by-default initiative, so the toggle may no longer be available in newer deployments or regions.

    The default *.azurewebsites.net endpoint should continue to function, but it's now provisioned with the secure hostname configuration automatically. If you're using Infrastructure as Code (Bicep, ARM, Terraform, or Azure CLI), it's also worth checking whether your deployment templates need to be updated to align with the new behavior.

    I'd be interested to know whether anyone has seen an official Microsoft announcement or release note confirming this rollout, as I haven't found a definitive communication yet either.
