title: No Availability Zones available in Azure North Central US Region
body: <p>I'm deploying a global networking solution and using Terraform as my IaC solution.  I have ExpressRoutes, VPN Gateways, Vnet-to-Vnet connections etc.</p>
  <p>I've deployed a VPN Gateway in Azure North Central US and now when I come to deploy and IP address for it I can't.  By default I use Zone-Redundant availability zones.  Ie. Zone 1, 2 and 3.  When I try to deploy an IP using Terraform, I can't use any of the available options - no zone string list, no single zone, not the <em>No-Zone</em> or <em>None</em> parameter.  All I get is an error from the MS API saying the available zones for the region are ''.  It's literally empty.</p>
  <p>If I deploy it manually then get the IP properties of the address it shows the zones as an empty array.  Are MS experiencing issues right now?  I find it incomprehensible that the North Central US zone which is the regional pair of South Central US (which has 3 availability zones) has...<strong>no zones</strong>.  I'm confused.  Could someone share their experiences please, and advise whether this is a temporary issue.  I scoured the internet and found nothing.  I'm normally working in the European Azure regions so this is the first time I've used this particular one.</p>
