To prevent test domain names of Function and Pages from being abused, ESA gradually adds token authentication and rate limit to test domain names (with the suffix er.aliyun-esa.net) from April 7, 2026. Access to test domain names without authentication or with excessive frequency will be denied.

Impact

1. Authentication information will be added to the redirection link of the test domain name. Clicking the redirection link in the console or copying the redirection link (valid for 60 minutes) will not be affected.
2. Access to the test domain name without authentication information, or with excessive frequency will be denied. Domain names with er.aliyun-esa.net suffix are only for testing. Do not use the domain names for production.

We recommend that you bind the function and Pages application to your own domain using the "Domain Names" feature, and then use your own domain for production environment use.
