RFC.fyi: Browse RFCs by keywords, id or collection
I tried one of the example queries, "UDP".Out of the 45 search results, the most relevant one (the UDP RFC itself) was all the way at the bottom, listed as "RFC0768" and tagged as "legacy". (I'm not sure what legacy actually means here?)Anyway, I clicked the link, which took me to a 404 error page - https://www.rfc-editor.org/rfc/rfc0768.html (The correct URL is apparently without the leading 0)This site does seem genuinely useful, but I think the UX could really use some polishing here, especially since I literally followed through with one of the example queries in the middle of the homepage.
