As a Johanna resident you have access to super fast internet. The internet is centrally distributed via the SSH network. All SSH complexes have been merged and are managed by the Abuse group. There is nothing wrong with normal use of the Internet connection. However, the SSH uses a fair-use policy as a network administrator. This means, among other things, that there is an upload limit of 100 gigabytes per week. If you go beyond this use, the SSH can turn off your internet. This will not happen without warning. If you have a virus on your computer, you can be shut off immediately.
