San Francisco Metropolitan Internet eXchange — a community-driven and operated Internet Exchange in the San Francisco Bay Area since 2006. Keeping Bay Area traffic local since before it was cool.

The public-facing Hugo static site now lives in its own repo: sfmix/website. Deployed to web.sfmix.org via GitHub Pages.

Ansible roles and playbooks that keep the lights on — network devices, servers, and services. Highlights include:

• sfmix_arouteserver / sfmix_route_server_linux — route server config generation (ARouteServer) and BIRD deployment
• sfmix_looking_glass — looking glass and participant data publishing
• sfmix_network_devices — peering switch configuration management
• sfmix_website — provisions the web server (nginx, Let's Encrypt TLS, deploy user for CI/CD)
• sfmix_dns — authoritative DNS zone management
• snappy — the speed test stack (LibreSpeed, OpenSpeedTest, TAUC TR-143, iperf3)
• …and more (monitoring, flow collection, RPKI, etc.)

A multi-frontend looking glass for IXP operations, written in Rust. Provides telnet (public), SSH (authenticated via OIDC), REST API, and MCP interfaces. Queries Arista EOS and Nokia SR-OS devices. Deployed on alice.sfmix.org as split-mode services (lg-server, lg-cli, lg-http).

Django-based IXP participant portal at portal.sfmix.org. Fetches participant and network data from the looking glass REST API.

Local development environment — Containerlab virtual network topologies, NetBox Docker, and monitoring stack for testing changes before production.

Terraform configs for managed services (Authentik SSO at login.sfmix.org).

Handy Python utilities for day-to-day IXP operations:

• new_participant.py — interactively onboard a new participant in NetBox, finding available pre-patched switchports
• discovery.py — ARP/NDP MAC discovery, VLAN→interface mapping, and NetBox updates
• route_server_parity.py — compare BGP session state across route servers to find participants missing parity
• participant_speeds.py — port speed reporting by site and in total
• netbox_ix_lint.py — lint and validate NetBox IX data

Public SFMIX docs — BGP community references, Nokia SR OS cheatsheet, NetBox conventions, and design docs. Private documentation lives in sfmix/documentation.

ESPHome configs for environmental sensors deployed at IX sites. Because even bits like it cool.
