Description
Connection draining is a process that ensures that existing, in-progress requests are given time to complete when a virtual machine (VM) instance is removed from an instance group or when an endpoint is removed from network endpoint groups (NEGs).
Performance best practices recommend configuring connection draining timeout to allow existing requests to complete when instances are removed from a backend service.
Remediation
Set connection draining timeout on an existing backend service.
