Broken links policy/monitoring

Hey Web Team,

I noticed that there are a bunch of broken links in the "Who's using
Debian" English commercial pages:

    tubaman@potts:~/sandboxes/webwml [who_updates_20200610]$ find english/users/com/ -name "*.wml" | xargs grep "define-tag webpage" | sed 's/.*<define-tag webpage>\(.*\)<\/define-tag>/\1/' | xargs -P 20 -n1 -I{} curl --write-out "{} %{http_code}\n" --location --silent --output /dev/null {} | grep -v " \(200\|30.\)\$"

Do we have a policy around removing/fixing broken links?


Do we currently actively monitor the site for broken links?


Thanks!
