+## Where penguins meet
+
+Do you know where penguins live? Probably all of us assume that they
+live at the South Pole. That is correct. And it is [a really
+fascinating story how penguins
+meet](https://en.wikipedia.org/wiki/March_of_the_Penguins). If you
+haven't seen the movie, we can highly recommend it!
+
+But did you know that penguins also live and meet at other places? For
+instance [in Africa](https://en.wikipedia.org/wiki/African_penguin).
+Or in the case of the penguin companies [South
+Pole](https://www.southpole.com/) and [ungleich](https://ungleich.ch):
+in Switzerland.
+
+This blog post is about how penguins and ethical values brought South
+Pole and ungleich together.
+
+## Who is South Pole?
+
+South Pole is a 350-people team of passionate climate experts with its headquarters in Zürich. It provides global climate solutions and develops projects for companies and organizations embarking on their Climate Journey, which includes assessing their carbon footprint and climate risks, green investments, carbon neutrality, and renewable energy.
+
+Started as a handful of people with great ideas back in 2006, now their offices are spread over 18 countries, including Singapore, London, Amsterdam, Sydney, Stockholm, and more. And most importantly: their mascot is a penguin, and the team calls themselves the Penguins.
+
+Sustainability, Switzerland, penguins?! Instant love for us.
+
+We recommend that you take a look at [the South Pole
+blog](https://www.southpole.com/blog) that covers inspiring
+projects such as forest conservation, wild animal protection, clean
+water project for local communities, and many more.
+
+
+
+## Sustainability at ungleich
+
+A few years ago ungleich started building data centers in
+[the Canton of Glarus in Switzerland](https://en.wikipedia.org/wiki/Canton_of_Glarus).
+This valley does not only offer a gorgeous view, but was the home of
+the weaving industry for more than a century. And it's our luck and
+privilege to build on top of this heritage.
+
+Our focus is on re-using and re-modeling buildings from this
+time. Many factory halls in Glarus also come with on-site hydropower
+plants, which allows us to run servers on 100% renewable, locally
+produced power.
+
+Not only do we re-use old buildings, but with recycled hardware,
+we were all in for creating a data center that is
+as sustainable as possible.
+
+When we started this project it was not 100% clear for us what kind of
+people would be interested in this kind of hosting.
+
+
+
+More and more we are realising that how we started and continued our
+journey has actually brought us the best kind of people. The kind
+who shares our visions of sustainable technology and understands the
+value of what we do. So such was the case for team ungleich and team
+South Pole. We love that those whom we provide our services to have
+the same mission as we do. Enabling and supporting like-minded people
+with what we have built has been a really exciting journey for our
+team.
+
+## Continuing our work on sustainability together
+
+South Pole is offering a variety of
+[Sustainability
+Solutions](https://www.southpole.com/sustainability-solutions) in all
+kinds of areas. At ungleich we focus on sustainable hosting in the
+[Data Center Light](https://datacenterlight.ch/), the renewable
+energy-powered data center in the Alps. And we are proud to say that
+South Pole hosts data in the Data Center Light.
+
+Together we can make a change for a better world.

+### Bounty 5: Allow wireguard to automatically switch the underlying IP version

+If you establish a VPN connection with wireguard, it resolves the
+hostname in your configuration and remembers that IP address.
+
+This is problematic, because if you connect to the VPN server in an
+IPv6 only network and then later switch to an IPv4 only network,
+wireguard will never reconnect. The same problem appears if you switch
+the other way round.

+We offer a __150 CHF__ bounty for the person who successfully

+On the wireguard mailing list it was discussed whether a peer can have
+multiple IP addresses. This could be a proper solution, as it also
+addresses the case when a VPN server has multiple IPv6 or IPv4
+addresses.
