The resource is gone permanently and no forwarding address is known.
410 Gone is a stronger 404: the server knows the resource used to exist, has removed it on purpose, and expects the removal to be permanent. Search engines drop 410 URLs from the index somewhat faster than 404s. 410 is heuristically cacheable.
