Managed Backend Tier Reconfiguration In Progress

URI: https://docs.ankatech.co/errors/managed-tier-binding-in-progress
HTTP Status: 409 Conflict

When you see this

A reconfiguration of this ANKA-managed key-protection tier arrived while the tier was already transitioning: its persisted state is BINDING from another operator's in-flight request. The refusal is what stops two concurrent reconfigurations of the same tier resolving last-writer-wins on a custody claim. Nothing was changed by the refused request.

Common Causes

  • Two platform operators reconfiguring the same tier at the same time.
  • Re-submitting the tier selection before the previous request finished.
  • A binding window opened moments ago by another console session on the same tier.

How to Resolve

  1. Wait for the in-flight reconfiguration to complete, then retry. This condition is transient by design.
  2. Re-read the tier before retrying — the change that was in flight may already be the one you intended to make.
  3. If a reconfiguration was abandoned by a process that died mid-transition, the window is reclaimed automatically once it is old enough, and the retry then proceeds.
