2/3 It took me 2 workdays investigating, diving into #Lingualibre +#Commons + Meta's #SPARQLs, logs and APIs (recentchanges with tagfilter=lingualibre, userrights).

But there we are ! ✌️
1) massive collapse of uploads was observed
2) bug was replicated and error message was identified
3) unblock request made ! thk @ancilu , and the large ban block was reconfigured.
4) we are back online !
