We're reworking our current NTP infrastructure and are looking for public NTP stratum-1 servers (we don't currently have the resources to run our own stratum-1 at this time) that are willing to allow one of our stratum-2's to get and distribute time from. We'd like to use MD5 authentication and so far I've had limited success in 1) just getting any response from nearby stratum-1's, but also 2) finding public stratum-1's that will do MD5. Before I start going down the list and bugging stratum-1 admins in other regional areas on David Mill's public list, is there anyone who operates or knows of a stratum-1 that will offer this service for us (and someone or someplace I can marginally validate the trusthworthiness of :-). Replies are probably best off-list unless you want to broadcast to the world that you offer such a service. Thanks in advance, John
