Infrastructure

Yes, it's been subsumed by https://stats.documentfoundation.org which uses a different backend. https://downloadcounter.lo was never really widely advertised and was visited only rarely but I guess we could add a redirect.

The counter was actually at https://downloadcounter.libreoffice.org/test

By the way, the data seems to have changed with the new download counter.
You can compare the old data (https://web.archive.org/web/20190802113142/https://downloadcounter.libreoffice.org/test)(see https://commons.wikimedia.org/wiki/File:LibreOffice_and_Apache_OpenOffice_downloads_per_week.svg for its visualization) to the new one (https://stats.documentfoundation.org/data/downloads.json). I wonder which one is correct.

The new one also has more precision for the last few months (downloads per day) but the downloads per week aren't available after two years.

Added the redirect now:

$ curl -so/dev/null -w"%{http_code} %{redirect_url}\\n" http://downloadcounter.libreoffice.org/
