Change and Impact
Thank you for your support of Alibaba Cloud. To improve our backup services, we are upgrading the underlying backup infrastructure. This upgrade will result in a change to the outbound IP address of the servers; therefore, you will need to reconfigure the backup allowlist to ensure the stable operation of your business.
Action required
If you have online services that rely on this feature, we recommend configuring a new backup IP whitelist before the upgrade date to avoid service disruption; please refer to the documentation on adding whitelists. Backups must be performed in the planned regions, and the corresponding regions must be added to the allowlist. The regions and allowlist details are as follows:
| Region | IP Allowlisting |
| Hangzhou | 100.104.115.64/26 |
| Beijing | 100.104.196.0/26 |
