Symptoms
- One key fails while another key on the same account works.
- The key management page shows its configured limit consumed.
Likely causes
- The key has a finite quota that is exhausted.
- A shared workload consumed the limit sooner than expected.
How to diagnose
- Review the specific key’s configured and consumed quota.
- Confirm which service instances share the key.
- Separate account balance from per-key limits.
Fixes
- Raise or reset the key limit only within the intended budget policy.
- Create separate keys for independent workloads and owners.
- Add usage alerts before the next limit is reached.
How to verify
The intended workload succeeds with a key that has remaining authorized quota.
