That article has been updated frequently (last updated in Jan 2021 https://github.com/MicrosoftDocs/SupportArticles-docs/commits/main/support/iis/http-status-code.md), so you'd better describe what you meant by "more current". What error status code does it miss? Note that it is intentional to cover only a few (common) error status codes in "Common HTTP status codes and the causes" section.

@Karl Von Winkle Your document link and content basically contain all HTTP status codes, usually HTTP status codes are not updated, what do you mean? Here is an HttpStatusCode Enum can supplement your content: HttpStatusCode Enum.
