Can I Use WAF Across Regions?
Generally, a WAF instance purchased in any region can protect web services in all regions. To make a WAF instance forward your website traffic faster, select the region nearest to your services.
If you purchase WAF in the Beijing region, services on other regions (for example, Shanghai) can also be protected by WAF. However, it takes a longer time for WAF to forward traffic of services in Shanghai. Therefore, you are advised to purchase two WAF instances, one in Beijing and another in Shanghai, to protect services in Beijing and Shanghai, respectively, improving the forwarding efficiency.
