It seems that notifications are broken at `HEAD` (I just updated this morning). I can reproduce this by going to https://secure.phabricator.com/notification/status/ and clicking the "Send Test Notification" button... no notification is generated.
Running the Aphlict server in debug mode and it seems that the Aphlict client isn't connecting to the server:
```
josh@ip-10-154-233-161:/usr/src/phabricator$ sudo -u aphlict ./bin/aphlict debug
Starting Aphlict server in foreground...
Launching server:
$ 'nodejs' '/usr/src/phabricator/support/aphlict/server/aphlict_server.js' '--client-port=' '--admin-port=22281' '--admin-host=notifications.phabricator.example.com' '--log=/mnt/logs/phd/aphlict.log'
