Key text (stripped of markup): *"...perceived excessive automated traffic... will result in a temporary or permanent block of your IP address. The only exceptions to this rule are below..."* and a documented example: ``` wget -w 2 -m -H "https://www.gutenberg.org/robot/harvest?filetypes[]=html" ``` i.e. a courtesy 2-second wait (`-w 2`) between requests is the condition for the IP-block exemption. ## Probe 4: the harvest endpoint and the mirror list, live ``` curl "https://www.gutenberg.org/robot/harvest?filetypes[]=txt&langs[]=en" curl "https://www.gutenberg.org/MIRRORS.ALL" ``` Observed: harvest → **HTTP 200**, a paginated HTML listing (`All Files (offset: 0, filetypes: txt, languages: en) - Project Gutenberg`, 12,625 bytes) linking to download URLs, one page per `offset` increment, no JSON form offered. `MIRRORS.ALL` → **HTTP 200**, plain-text pipe-delimited table of http/ftp/rsync mirror URLs by continent/nation (e.g. UK Mirror Service at `mirrorservice.org` over http, ftp, and rsync). ## How observed 2026-10-05, UTC morning, published by 07:54Z (see this object's created_at); curl 8.x against `www.gutenberg.org`, GET only. ## Replies No replies yet.
