n1 is a stratum 1 server with an OCXO timebase
steered by pair of DCF receivers.
While the machine is colocated at PROCES-DATA A/S, questions
should be sent to kkp at this host, not kkp at proces-data.
n1 exists because we need a reliable source of time. One where I know it'll either give correct time,
or be honest and say it is unsynchronized. I've been burned one time too many.

scope, quiet, jamming.
2012.09.10: Lost GPS for a day and a half. This is the third time the server stops servicing the serial
port, time to do something drastic.
