Petr Bena told me about the HTML-formatted bot logs, so I added a mention to https://meta.wikimedia.org/wiki/Office_Hours#Office_hour_logs
but it seems they stopped in August, see the URL http://bots.wmflabs.org/~wm-bot/html/%23wikimedia-office/?C=M;O=D. If you visit the parent directory (http://bots.wmflabs.org/~wm-bot/html/?C=M;O=A , slow!) it has some more recently updated subdirectories, but all the ones I checked are empty.
Version: unspecified
Severity: normal
