This isn't related to what happened last night
but,
while I was grinding at the Sardegna 800 two nights ago I saw a message at the bottom right corner of the screen saying I went offline. As a result my progress wasn't saved and menu screens after the race were loading endlessly because of that online only thing.
Searching on Downdetector I figured my ISP was having NAT issues (very, very rare, happened only twice since september 2021).
But technically speaking, PD and Sony's ARE the source of the problem since THEY implemented this mandatory online only "feature". Never bothered me before the outrageous long outage, but now....
