Using Azure Front Door for access to a multi-region Azure web app does indeed meet the goals of rate limiting and regional outage support. Azure Front Door is a global, scalable entry point that enables high availability and low latency for your applications.

One of its key features is the ability to implement rate limiting, which allows you to control the amount of traffic that is permitted to reach your web application. This is particularly useful in preventing abuse or excessive usage from certain users, thus ensuring that resources remain available for legitimate users.

In addition, Azure Front Door supports multi-region deployments by intelligently routing traffic to the nearest CDN endpoint or to a healthy endpoint if one region experiences an outage. This capability ensures that even if one of the regional web app instances goes down, users are still directed to a functioning instance, maintaining the availability of your application across different geographical areas.

Together, these features not only enhance the performance and reliability of web applications but also provide robust support for operational continuity during regional outages. Thus, utilizing Azure Front Door effectively aligns with the goals of achieving rate limiting and ensuring support during regional outages.
