Do records disappear
First of all, thank you for making info available.
Do the records just disappear overnight or are you loading different records every day?
Honestly i found records of family members now all of a sudden there nothing available.0
Records don't disappear. Sometimes contracts with the record holders change, and the images can no longer displayed to researchers at home. They may still be available at one of the restricted locations - the FHL in Salt Lake, local FamilySearch Centers, or Affiliate Libraries.
If you have specific records you would like to find, someone may be able to help you locate them or suggest a different way to search.1
