Change schedule: 14:00 on July 10, 2023 (Beijing time) to 14:00 on July 13, 2023 (Beijing time)
Change content: Change resolved CIDR blocks for internal endpoints of Alibaba Cloud Object Storage Service (OSS) in the South Korea (Seoul), Australia (Sydney), and US (Silicon Valley) regions.
Impact: After the change, the use of OSS is not affected if you use official internal endpoints. However, if you use the resolved IP address or CIDR block of an internal endpoint, change the resolved IP address or CIDR block to a new resolved IP address or CIDR block at the earliest opportunity. The following section describes the resolved CIDR blocks for internal endpoints of OSS in the involved regions after the change. For more information, see the OSS documentation.
● South Korea (Seoul) region (region ID: oss-ap-northeast-2): Change the resolved CIDR block for the internal endpoint oss-ap-northeast-2-internal.aliyuncs.com/*.oss-ap-northeast-2-internal.aliyuncs.com to 100.99.119.0/24.
● Australia (Sydney) region (region ID: oss-ap-southeast-2): Change the resolved CIDR block for the internal endpoint oss-ap-southeast-2-internal.aliyuncs.com/*.oss-ap-southeast-2-internal.aliyuncs.com to 100.98.201.0/24.
● US (Silicon Valley) region (region ID: oss-us-west-1): Change the resolved CIDR block for the internal endpoint oss-us-west-1-internal.aliyuncs.com/*.oss-us-west-1-internal.aliyuncs.com to 100.115.107.0/24.
