RU-3011: Region outside plan entitlement

One or more requested probe regions are not included in this account's plan (REA-484). realuptime refuses this explicitly rather than silently dropping the out-of-plan region, so the check's stored regions always match what the dashboard shows.

On the wire

Ships with HTTP status 400, carrying "code": "RU-3011" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.

Common causes

  • Selecting a Growth- or Scale-only region (e.g. London, Singapore, Sydney, Toronto, Chicago, São Paulo) on Free.
  • Selecting a Scale-only region (Toronto or São Paulo) on Growth.
  • An account that downgraded and still has an out-of-plan region selected on an existing check (existing checks are not truncated -- see updateCheckRegions' doc comment -- but cannot be RE-saved with the same out-of-plan region).

How to fix it

  1. Select a region included in your current plan (see /pricing for the per-tier region list).
  2. Upgrade to a plan that includes the region you need.
