INITIAL ALERT

Authorized users can list objects but cannot download encrypted content.

You are primary on-call. Establish the failure domain, protect healthy capacity, and choose the safest next action.

KNOWN-GOOD BASELINE

S3 GetObject is allowed and the object key exists.

The decisive evidence and solution remain locked inside the simulation.

WHAT THIS TESTS

Production judgment across S3 · KMS.

Storage can be available while data is unreadable, unexpectedly archived, throttled, or quietly accumulating cost. The evidence lives across service state and policy layers.

  1. 01Separate availability from data access
  2. 02Inspect encryption and lifecycle controls
  3. 03Balance recovery, durability, and cost

SIMULATION STRUCTURE

Four evidence layers. No answer shown here.

The full exercise unlocks each layer as you commit to decisions.

03

Finding

Identify the evidence that separates plausible causes.

04

Change

Choose a controlled recovery and a durable prevention step.
