Mastodon.at is a public Mastodon instance and federates with all other instances with the exception of those with community values that are overwhelmingly incompatible with our Terms of Service. Our primary languages are English and German, but other languages are more than welcome.
Mastodon.at is maintained by an experienced sysadmin. User data is backed up to multiple locations at least once every hour to avoid data loss. Our backend server is hosted in France. We also operate an edge node in the United States.
