Why has this source disappeared (and cannot be found in at https://www.familysearch.org/search/)?

Paul said: This census source (1861 England & Wales) is no longer available. I thought the URL might have changed without it replacing the original one, but a (wildcard) search at https://www.familysearch.org/search/ did not locate any available 1861 census source for Mathew. Any ideas on how to get it back? (Note - I don't seem to be having problems with other sources from this collection.)

Thanks for the report and your patience.

A typical situation where I encounter 410 errors is illustrated below. In these cases the original collection is withdrawn and replaced, using a new set of URLs. The "new" source then appears under Record Hints so, as in this case, it can immediately be added to the Sources section.

The replacement source (with new URL) is shown above the withdrawn one:
