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.

No, it is the Iranian government shutting down the internet.

They are almost certainly attempting to shut down communications due to the ongoing anti government 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!

Why would they want to block IPv6 specifically?

(going with recent ipv6 discussion) they probably failed to make it work properly and decided that it's easier to block it

IDK for sure, but might be harder to maintain, monitor, and block.

One characteristic of v4 is it's somewhat reasonable to do a straight forward block on a range of addresses to shut down access. This is still somewhat possible with v6, but harder as there's simply a much larger portion of ip addresses that can be all over the place. It's theoretically a lot easier for anyone that wants to bypass a simple filter to grab a new public IP address.

Not specific to this IPv6 event, but I was wondering what happens to public services during these Internet shutdowns?

Does everything stop or it's mostly business as usual minus some things?

I would imagine hospitals, tax offices etc need the internet to work?

In recent years they have been trying to build a nation-wide Intranet that can function while international gateways are blocked. It is not perfect and every time they block the Internet, many issues happen but for the most port critical network services (such as payments) continue to function.
