Thank you for your support to Alibaba Cloud. As ecs.ebmc4.8xlarge and ecs.ebmhfg5.2xlarge physical servers are outdated and out of warranty, there is a risk of mass downtime and cannot continue to provide high-availability service quality commitments. The ebmc4 and ebmhfg5 instances will cease service and be taken offline at 00:00:00 on September 15, 2026, Beijing Time. We recommend that you migrate related instances to other instance types via the "Change Configurations/Change Instance Type" method. We suggest prioritizing migration to the ecs.hfg5, ecs.hfg6, ecs.c5, ecs.c6, ecs.g5, and ecs.g6 instance families. After migration, the instance name and instance IP will remain unchanged.

If your online business relies on the ecs.ebmc4.8xlarge and ecs.ebmhfg5.2xlarge instances, we recommend completing the migration operation before the upgrade date to avoid service interruptions.
