Note:
It is recommended to keep the region of the SaaS WAF instance consistent with that of the Web origin server to effectively reduce business latency.
Cloud Native WAF implements protection for IPv6 websites by binding IPv6 CLB. If you need IPv6 website protection, please confirm in advance whether the selected region supports creating IPv6 cloud-native instances and that IPv6 website deployment has been completed.
IPv6 cloud-native instances are supported in most regions. The actual supported regions are subject to the regions displayed on the CLB Purchase page. For more information about IPv6 CLB support, see Getting Started with IPv6 CLB.
WAF can Contact Us for region change when no domain name protected by SaaS WAF has been added. Region change is not supported if domain names protected by SaaS WAF have already been added.
