\item 2012: Neustart. Wachstum auf mehr als 1100 Knoten und 2500 Nutzer*innen
|

\item Früher: VPN ins Ausland
|
||||
\item Professionalisierung: Providerstatus, Autonomes System, Internetzugang in Deutschland
|

\item Ab 2013 in Hamburg: Versorgung vieler Flüchtlingsunterkünfte
|

\item Deutschlandweites Thema für Freifunk
|

\item (Un)regelmäßige Plena mit Mehrheitsentscheid

\item Steigende Komplexität führt zu größerer Einstiegshürde

\item Im Rahmen der Professionalisierung entstanden:\\
|

Freifunk Rheinland e.V. und andere lokale Vereine
|

\item Italien: ninux.org als reines Intranet
|

\item Spanien: guifi.net als offenes Netz mit kommerziellen Anbietern \& Kostenteilung
