Sometimes an Archive.org capture shows too many requests instead of the site:
I think (but I don’t have a link) that this has also happened for individual questions, which is bad because there might only be one capture of said question. I try to use Archive.org for recovering dead images and it always feels like a slap in the face when I see this.
It’s not possible to give anyone/anything no limit but I think the site should have less limiting.
(Also it should be “an unusually high number” in the error message.)
