Technical Details

kosmos.social is currently hosted on a dedicated server at Hetzner in Germany (renewable energy source, German laws apply). We configure and deploy everything via Chef cookbooks. Your uploads are stored on Amazon S3. Automated backups are run regularly and pushed to S3 as well.

Our fork of the source code is publicly available at https://gitea.kosmos.org/kosmos/mastodon/ (we deploy the production branch). We frequently update the repo and running code with the latest fixes and improvements.

TL;DR We know what we are doing and your data should be safe. However, since this is a free service, we do not guarantee it.

Chat rooms

If you're using IRC, you can find us in #kosmos on Libera.Chat. XMPP users are invited to join kosmos@kosmos.chat. If there's no immediate response to a question, just idle for a while.

Tor

You can access this instance from within the Tor network at the following address:

http://mastodon.http://mastodon.uepfmeoecnl3wbdecldvw5sjtbwv3f43gwcwi6hxlj5pavlidodob5qd.onion/

Please note that there will be a security warning about the TLS certificate being valid for the "wrong" domain. It is using the "kosmos.social" certificate, so you can verify that it's the correct site and grant an exception for this mismatch. A small orange warning icon will persist in your address bar, even though the connection is actually quite secure.
