I'm adding a google load balancer and the ssl will take a while to provision and propagate. Is there a way that I can put up a server maintenance page while waiting for the propagation to complete?
I can put up a server maintenance page while waiting for the propagation to complete?
No. Until the propagation completes, users cannot get past the load balancer to see your maintenance page.
Note: The HTTP and HTTPS listeners operate independently. This means that if you configure the HTTP listener before configuring the HTTPS listener, in most cases, HTTP traffic will continue to flow to the backends while the HTTPS listener is configured - unless your domain is using HSTS or permanent HTTPS redirects.
