err:unkey:data:ratelimit_namespace_gone
ratelimit.limit or ratelimit.multiLimit named a rate limit namespace that was deleted. You get HTTP 410.
Example response

Likely causes

  • The namespace was deleted. A deleted name can’t be reused. Normally ratelimit.limit creates a namespace the first time you use a name, but for a deleted name it returns this error instead, so an accidental delete can’t turn into unlimited traffic.

How to fix

  1. Use a new namespace name.
  2. Or, if you need the old overrides and history, ask support to restore it.
Don’t delete a namespace to reset its counters. Only delete one you’re retiring.
