Upgrade window: 23:00 Sep 13th to 01:00 Sep 14th , 2021, Beijing time
Upgrade content: Anti-DDoS Premium network in Britain region update
Upgrade impact: During the upgrade, some IPs subject to stronger security checks will need to be re-authenticated, which will cause the TCP connection to be interrupted briefly 1 time. This will have minimal effect on short-term connections and long-term connections which have an automatic reconnection mechanism.

Please make sure that you have a reconnection/retry mechanism in your application to enhance fault tolerance.

We apologize for any inconvenience caused. If you have any questions, please feel free to contact us by submitting a ticket any time.
