An mTLS allowlist updates and one service still trusts the retired client CA because SDS warmup serves the old secret name

The new CA bundle is present, but one worker warm path still maps the older secret name during startup.

Scenario

One service still trusts a retired client CA after allowlist rotation.

What to check first
  • Identify the primary failure signal in the TLS scenario.
  • Separate visible symptoms from the underlying technical dependency.
  • Describe the safest recovery path and the follow-up prevention work.
Checking checklist
  1. Summarize the current impact and the last known change.
  2. Collect direct evidence from logs, runtime state, and configuration before changing anything.
  3. Separate immediate recovery from permanent prevention work.
Recovery and prevention

Inspect SDS warmup before reissuing service certs.

Questions worth viewing together
Should I translate commands, logs, or product names?

No. Keep commands, logs, file names, APIs, and product names unchanged, then explain the reasoning in the selected UI language.

What should the answer focus on?

State the root cause, the evidence that supports it, and the safest recovery direction.

Why can the scenario remain in the original language?

The source scenario is treated as an incident artifact. Guidance, checklist, hints, and explanations can be localized around it.
