AWS WAF is now available in the Canada West (Calgary) Region

Starting today, AWS WAF is available in the AWS Canada West (Calgary) Region. This is the second Region in Canada where AWS WAF is available, joining the AWS Canada (Central) Region, and giving customers more choice and flexibility. AWS WAF is a web application firewall that helps you protect your web application resources against common web exploits and bots that can affect availability, compromise security, or consume excessive resources. You can protect Amazon CloudFront distributions and Application Load Balancer in the AWS Canada West (Calgary) Region. Support for other AWS resource types, such as Amazon API Gateway REST APIs, is expected later. With AWS WAF, you can control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, your protected resource responds to requests either with the requested content, with an HTTP 403 status code (Forbidden), or with a custom response.
