# ADR-002: Host Selection — Hermes VPS

**Status**: Accepted  
**Date**: 2026-04-05  
**Deciders**: Ezra (architect), Timmy Foundation  
**Scope**: Initial deployment host for Matrix/Conduit (#166, #183, #187)

---

## Context

We need a target host for the Conduit homeserver. Options:
- Existing Hermes VPS (`143.198.27.163`)
- Timmy-Home bare metal
- New cloud droplet (DigitalOcean, Hetzner, etc.)

## Decision

Use the **existing Hermes VPS** as the initial host, with a future option to migrate to a dedicated Matrix VPS if load demands.

## Consequences

| Positive | Negative |
|----------|----------|
| Zero additional hosting cost | Shared resource pool with Gitea + wizard gateways |
| Known operational state (backups, monitoring) | Single point of failure for multiple services |
| Simplified network posture | May need to upgrade VPS if federation traffic grows |

## Migration Trigger

If Matrix active users exceed ~50 or federation traffic causes >60% sustained CPU, migrate to a dedicated VPS. The Docker Compose scaffold makes this a data-directory copy.
