05 ANSWER-SAFE INCIDENT BRIEFS
AWS storage incident practice
Practice S3, KMS, EBS, lifecycle, versioning, and storage-cost investigations through production-style incident briefs.
WHY THIS TRACK MATTERS
Debug the system, not the first plausible theory.
Storage can be available while data is unreadable, unexpectedly archived, throttled, or quietly accumulating cost. The evidence lives across service state and policy layers.
- Separate availability from data access
- Inspect encryption and lifecycle controls
- Balance recovery, durability, and cost
INCIDENT QUEUE
Choose the failure you want to face.
Each preview shows the symptom and baseline while keeping the diagnosis and recovery protected.
INC-018Advanced
KMS allows the bucket, not the reader
S3 · KMS
authorized users can list objects but cannot download encrypted contentINC-019Foundational
Deleted but still there
S3 · Versioning
a previously available object now returns 404 after cleanupINC-020Intermediate
Lifecycle freezes hot data
S3 · Glacier
a batch job cannot immediately read recently archived objectsINC-021Advanced
The EBS burst bucket empties
EBS · EC2
disk latency spikes during sustained writes without a volume failureINC-022Intermediate
Multipart uploads never leave
S3 · Cost
storage charges rise even though visible object count is stableFULL SIMULATION LIBRARY
