 Connect in to dn42 using a real physical modem.
 
 {{<hint danger>}}
+**06/02/23** - The modem service is currently unavailable and will remain offline until later in the year.
+
+In the meantime, the [modem emulator](https://wdev.burble.dn42/retro/fake/) service is still available.

 **Health warning**: dialing in to dn42 can be rewarding and great fun, but using modems
 over VoIP is flakey at the best of times and getting it to work can be a
 frustrating experience. This is very much an experimental service.
