What I do @ Tor

The admin team at the Tor project maintains our infrastructure and services.


Within the admin team we have sysadmins and services admins.


Sysadmins do not maintain every service that we offer. Rather, they maintain the underlying computers – make sure they get package updates, make sure they stay on the network, etc.


Then it's up to the service admins to keep their services (onionoo, atlas, blog, etc) working as intended.


  • 0-3 months: figurining out where I was ;)
  • 3-6 months: propose changes to services
  • 6-12 month: consolidate services and infrastructure
