Ultrain has recently completed the optimization of the network environment, and has officially activated the new domain name ultrain.info from now on, and switched the io suffix to the info suffix. This rule applies to all second-level domain names. At the same time, the API service interface is also migrated from ultrain.services to ultrain.info (see the developer documentation at https://doc.ultrain.info/#/docs-cn/developer/environment?id=��) %82%E7%82%B9%E4%BF%A1%E6%81%AF). The original domain name will still be accessible and will automatically be redirected to the new domain name.

Ultrain will continue to work hard to provide you with safer, more stable and faster access services, thank you for your continued support!
