Product: Alibaba Cloud Anti-DDoS Proxy (Outside Chinese Mainland)
Upgrade time: (UTC/GMT+08:00) 00:00:00 to 04:00:00 on December 25 and 31, 2019
Upgrade details: A network upgrade will be performed on the China (Hong Kong) and Malaysia data centers for Anti-DDoS Proxy (Outside Chinese Mainland).
Impact: The upgrade will not affect your services. In rare cases, some IP addresses may need to reconnect, which can cause 2 to 4 transient TCP disconnections. These disconnections have minimal impact on services that use short-lived connections or persistent connections with automatic reconnection. To improve fault tolerance, ensure your services have a reconnection and retry mechanism.
