## DN42 Wiki Mirror

|Mirror URLs||
|:--|:--|
|[wiki.dn42](https://wiki.dn42/)<br/>[wiki.burble.dn42](https://wiki.burble.dn42/)&nbsp;|(editable via DN42)|
|[dn42.dev](https://dn42.dev/)<br/>[wiki.burble.com](https://wiki.burble.com/)&nbsp;| (read-only via public internet)|

burble.dn42 maintains a globally distributed mirror of the DN42 Wiki, and is part of
the wiki.dn42 anycast group. 
The DN42 services ([wiki.dn42](https://wiki.dn42/) and
[wiki.burble.dn42](https://wiki.burble.dn42/)) are editable, whilst the public internet
views ([dn42.dev](https://dn42.dev/) and [wiki.burble.com](https://wiki.burble.com/)) are
read-only.

Please note that updates to the wiki may take several hours to sync with other mirrors.

The service is provided by regional mirrors fronted by an nginx proxy that is itself
anycasted across burble.dn42. The service is fully meshed and will continue to
operate as long as at least one proxy and mirror is available.

Mirrors are located in the following locations:

* dn42-de-fra1
* dn42-ca-bhs2
* dn42-us-dal3
* dn42-us-lax1

## Whois Service

* whois.burble.dn42
* fd42:4242:2601:ac43::1
* 172.20.129.8

[WHOIS](https://en.wikipedia.org/wiki/WHOIS) service providing data from the
DN42 registry. The WHOIS service is also anycasted across the network. 

The source code for the service is available in the
[burble.dn42 git](https://git.burble.dn42/burble.dn42/whois42d).

## Global Route Collector

* [https://grc.burble.com/](https://grc.burble.com/) (public internet link)
* [https://lg-grc.burble.com/](https://lg-grc.burble.com/) (public internet link)
* [https://collector.dn42/](https://collector.dn42/) (DN42 link)
* [https://lg.collector.dn42/](https://lg.collector.dn42/) (DN42 link)
* ssh shell@collector.dn42

The [global route collector](https://git.dn42.us/burble/grc) provides a central
bird instance that collects routes from peers across the DN42 network.  
All users are invited to join the collector and help provide stats for the network.

The route collector can currently be queried by using ssh to connect a bird shell
or via a looking glass.  
Additional services and stats are expected to be developed in the future. 

## DN42 Infrastructure Monitoring
