firewall_unavailable

HTTP 503 Cannot read the firewall of this server right now

What happened

The firewall of this server cannot be read right now. On a write request this can also mean the change was applied and only the read-back failed, so the state may already have changed.

What to do

Read the firewall again before deciding anything. If the state is still not what you declared, send the same request once more later.

Retrying

The request itself is fine. Repeat it later; after a 5xx use a new idempotency key and read the resource first.

Branch your code on code, never on the wording of title.
