Usage tracking facility for HTTP and FTP offline since server upgrade in early March

[wifiprintguy]

These pages aren't updating since server upgrade in early March:

https://www.pwg.org/usage/
https://www.pwg.org/ftp-usage/

Perhaps the facility that was gathering this information never got updated or re-installed...

OK, at least for the web site we have:

https://www.pwg.org/awstats/awstats.pl

I need to fix the link on the site menu, and I need to get FTP log analysis working, too.
