Topophany maps network reachability from the terminal
A self-hosted network monitor that maps machines, paths and services from named vantage points, with check evidence attached to each state.
- For
- Operators tracking services across network paths
- Worth noticing
- A CDN response proves the edge answered, not the origin; the page distinguishes that evidence from an origin check.
Field notes
The interface is organized around where a check ran and which path it tested, rather than treating every failed response as a server outage. The page says workers can send observations to two collectors and buffer during an interruption; it also describes journal writes being synced before acknowledgment. Its incident example keeps a possible routing or filtering explanation labeled as a hypothesis, with blocking authority and untested protocols left unestablished.
