After experimenting running a Tor relay server with Docker on Jelastic, we decided that we are going to invest into a dedicated server with unlimited traffic and higher speed rates. We stopped the Docker servers and startet the new Tor middle relay server "StarAppsMR01". In the future we even plan to add more servers and support the @torproject network and all the people who use it.
