Notice on changing resolved CIDR blocks for internal endpoints of OSS in some regions

Change schedule: 09:00 (UTC+8) on July 24, 2023 to 16:00 (UTC+8) on July 28, 2023

Change content: Change resolved CIDR blocks for internal endpoints of Object Storage Service (OSS) in the China (Fuzhou - Local Region), Japan (Tokyo), South Korea (Seoul), Thailand (Bangkok), US (Silicon Valley), UAE (Dubai), and SAU (Riyadh - Partner Region) regions.

Impact: After the change, the use of OSS is not affected if you use official internal endpoints. However, if you have used the resolved IP address or CIDR block of an internal endpoint, change the old 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 (https://www.alibabacloud.com/help/en/object-storage-service/latest/oss-internal-endpoints-and-vip-ranges).
