What it means#

We could not reach the calculation engine.

What to do#

Ours, not yours. Retry with exponential backoff; this class of failure is usually brief.

You were not billed. We meter only 2xx responses, so a failed call never consumes units. If it persists beyond a few minutes, quote the request_id.
