[swinog] Announcing mirror.init7.net

As SWITCH has announced the sunset of http://mirror.switch.ch/ a while ago we are happy to announce a successor mirror.init7.net.

https://mirror.init7.net

By supporting IPv6 and legacy IPv4 and https as well as legacy http we hope to be able to support the Opensource- and Internet-Community in the future.

In case your DNS resolver is broken we gave mirror.init7.net nice and easy to memorize IP addresses:

https://2001:1620::1620 https://109.202.202.202

We would like to express our gratitude to SWITCH for providing a mirror service for much longer than a decade.

PS. a hint for Debian and Ubuntu users - please ensure you have the package apt-transport-https installed to use https.
