Hi, I also noticed these broken links in the boost documentation for geometry. It made me wonder, whether there are more dead links in the boost documentation, so I tried to check that with a JS script. I only managed to get parts of the website running locally, and I didn't scan older versions than 1_70_0 recursively, so my results are definitely incomplete, but I did discover more broken links: The following documents list pages and below those pages is an unordered list of hyperlinks on those pages that seem to be broken. internal links that are probably broken: http://46.101.197.7/internal.html external links that are probably broken: http://46.101.197.7/external.html I'm not claiming that these lists are complete or without false positives but all links on it, that I checked manually, seem to be dead. Maybe the lists still help to see some broken links that might have gone unnoticed so far. Since link rot is natural, I wonder whether it would make sense to implement some check for this in the CI for the website so that breakages like this one could be discovered automatically in the future. I'd volunteer to implement that later this year but only if the general idea is considered sensible or viable by the boost website maintainers.
