Note:
We recommend you place your SaaS WAF instance and web real server in the same region to reduce business latency.
CLB WAF supports binding IPv6 CLB instances to protect IPv6 websites. If you want to use IPv6 web protection, make sure that the selected region supports IPv6 CLB instances and IPv6 web deployment has been completed.
IPv6 CLB instances currently support main regions. The supported regions are subject to the ones on the CLB purchase page. For more information on IPv6 CLB, see Getting Started with IPv6 CLB.
If you have never added a protected domain name in WAF, you can contact us to change the region. Otherwise, you cannot change the region.
