Are you aware that all the stats at the bottom of the homepage except for "ebooks borrowed" are zero?
Here's the issue: https://github.com/internetarchive/openlibrary/issues/5022
Sorry about that, on the docket for this upcoming week.
We're currently staffed by two eng (myself included) w/ ~80 open PRs, 500 issues, just finalized a py2 to 3 migration, and reprovisioned all of our servers w/ docker so we're playing catch-up on some newly surfaced issues.
Please do open such issues so we're aware! It's a huge way to help.
The issue mentioned above is happening because our cron jobs got moved from one machine to another.
Will reply here when resolved.
Seems other things came your way, but it seems like it's resolved now. There's plenty of stats on https://openlibrary.org/stats now and none are zero.
