Failure Log: Silent Automation Failure After Quota Exhaustion

This failure is usually discovered late.

Often weeks late.

What Failed

An automation hit a quota limit.

The script stopped running.

No one noticed.

Scenario: Silent Failure

Daily Quota

SYSTEM.LOG

ACTIVE

When the daily quota is hit, the script simply stops working. No error is thrown. The system logs look 'fine', but no emails are sent.

What It Looked Like

Emails not sent
Data not updated
No visible errors
Business processes quietly breaking

Root Cause

Quotas exist to protect systems.

But most automations are not designed to:

Detect quota exhaustion
Alert humans
Recover safely

So the system fails silently.

Why This Was Missed

Everything looked fine.

Until someone realised something had not happened.

How This Gets Fixed

Quota-aware design
Execution monitoring
Explicit failure alerts
Graceful degradation

The automation must know when it cannot run.

Prevention

Designing the failure path.

If failure is not modelled, silence is the default.
