Upgrade time: Beijing time 00:00-06:00 on February 21, 2019 (PST 08:00-14:00 on February 20, 2019)
Upgrade content: System upgrade will be performed in China Unicom China East, China Unicom China Northeast, US West and Germany Anti-DDoS Pro server rooms.
Impact of the upgrade: During the upgrade, there will be no impact under normal conditions. In extreme cases, some strong security check IPs will need to be re-authenticated, which may cause TCP connection flash. The flash will not affect the short connections and the long-connection services with automatic reconnection business. Please make sure your applications include a reconnection mechanism to ensure 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.
