+Protesters in HK encounter communcation disruption by Apple.
+This article shows how this can be avoided by using IPv6.
+---
+body:
+
+Recently
+Apple decided to [remove a central
+app for communication in Hong
+Kong](https://www.bbc.com/news/technology-49919459), just
+[to add it later
+again](https://www.bbc.com/news/technology-49961149).
+
+With this move Apple effectively disrupted the communication between
+people demonstrating in Hong Kong and at the same time endangered
+those who wanted to protect themselves from violance on the streets.
+
+In this article I want to show how this problem can be mitigated by
+the use of IPv6.
+
+## The core problem: centralisation
+
+The main problem is that we depend on centralised
+services. One of the questions is, why do we depend on centralised
+services at all? The reason for this is that there are not enough IPv4
+addresses and for that reason we use NAT to hide multiple devices
+behind one IPv4 address. Wait what? Let's take it a bit slower.
+
+## How NAT works
+
+In the old times of the Internet, every device in the Internet used to
+have a public IPv4 address. However when the number of devices began
+to exceed amount of officially available IPv4 addresses, NAT was
+introduced and it works as follows:
+
+![IPv4 NAT](/u/ipv4nat.png)
+
+Many devices are hidden behind one Public IP address. So for a phone
+to communicate with another phone, it needs to connect via a
+central, publicly available IPv4 server.
+
+## How IPv6 solves the problem
+
+In the IPv6 world, there are enough IP addresses available.
+So every device, every smart phone, every alarm clock, every computer
+can have a public IP address. Because every device can have a public
+IPv6 address, they can communicate directly with each other:
+
+![IPv6 direct connections](/u/ipv6direct.png)
+
+## How to communicate with IPv6?
+
+So how does it look like with IPv6? Instead of relying on a central
+entity (Apple in this case), you can directly connect to the phone of
+your friends. This way, you could even use your standard browser like
+Firefox, Chrome or Safari to write a message to your friend's phone.
+
+## So, what to do now?
+
+At the moment IPv6 is picking up pace in deployment and ISPs
+everywhere in the world are moving forward with it. However, if you do
+not have IPv6 connectivity, we [provide IPv6
+VPNs](https://ungleich.ch/ipv6/vpn/) that enable you world wide to
+have IPv6.
+
+## More IPv6

+If you are interested in IPv6, we invite you to join the [IPv6
+chat](https://IPv6.chat) or [follow us on
