5xx error - google console

Two URLS:

https://iiif.io/api/image/3.0/example/reference/899da506920824588764bc12b10fc800-bnf_chateauroux/full/256,256/0/default

and

https://iiif.io/api/image/3.0/example/reference/85a96c630f077e6ac6cb984f1b752bbf-5-21198-zz000228j6-1-master/full/100,/30/default

both work now but there isn't really any need to index these pages. So I'm going to exclude the following page from the index:

https://iiif.io/api/image/3.0/example/reference

as it is an example page of links into the image server but doesn't add anything to the website. There are also these pages:

https://iiif.io/api/image/2.1/example/reference
https://iiif.io/api/image/2.0/example/reference
https://iiif.io/api/image/1.0/example/reference
