Hello Leif!
Since you are listed as a Tor Admin for the Noisebridge Tor side, this email I hope finds its way to your Inbox.
We are soon about to reject all non supported relays from the network mostly for stability and security reasons:
https://trac.torproject.org/projects/tor/ticket/31549
We are in the process of contacting relay _and_ bridge operators about it.
It turns out that "noisebridge01" is in this category running Tor 0.3.3.9 which is End Of Life but also has a security issue.
https://metrics.torproject.org/rs.html#details/21D96945B790F10D00071BB3336F0...
This bridge is particurlarly important because it is shipped as a default obfs4 bridge in Tor Browser.
Depending on your OS, it would be grand to upgrade to our latest stable which is currently 0.4.1.5. You can find the list of our supported releases here:
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorR...
We are also starting a more long term effort to ask relay operators to keep up to date with our latest stable as much as possible (meaning _not_ the LTS) in order for the network to be able to upgrade faster and thus help reduce the very long migration path which is especially important for things like security issue at the protocol level.
Of course, if you are running Debian/Ubuntu, deb.torproject.org is the right place to start with:
https://2019.www.torproject.org/docs/debian.html.en
Let us know if we can help in any ways to make this transition easier.
Huge thanks! David
