Seems like v4s zeroed out for a tiny bit too, but even now they are substantially lower than normal. Odd behavior, I don't know if its a precursor to an attack or some infra issue

For IPv4 the graph does not start at zero, but at around 45K.

Considering the recent events going on, it’s definitely sus.

Probably more likely a internet blackout to counter the protests.

No competent network engineer wants to work in Iran, so government doesn't know how to block v6 properly. End result: just get rid of it entirely!

for context: There is a call to action from an opposition leader for people to join the protests today. They normally cutoff internet infrastructure on purpose in these cases so people cannot communicate

Stuxnet v2? Speculation I know, but wow, IPv4 came back up, but IPv6 is completely out, looks like 48 million devices? Compared to IPv4's 47 thousand (wow that's insane).

Looking at IPv6 its not 0 exactly, looks like probably censorship, only some devices allowed online? Some other comment mentioned there's calls to protest again today.
