A Gatus installation, which monitors all our websites and (external) services.
The status page can be found here: https://status.hamburg.ccc.de
There's also a Matrix room for alerts.
The Host as well as Gatus are configured in our Ansible repository.
Gatus is using a bot user on (matrix.)nekover.se for the Matrix status alerts. nekover.se was chosen, because it then also works when our Matrix is down and allowed us to get a personal session tokens, which wasn't possible on e.g. matrix.org.
