NIST Ion Clock Sets New Record for Most Accurate Clock in the World

Somewhat topical: in case you want authenticated access to NIST NTP servers, you need to send a letter to NIST using the US mail or FAX machine (e-mail is not acceptable).

NIST will reply with a key number and a key value. The reply will be by US mail only, e-mail will never be used.

The office that normally receives US mail and FAX messages currently has limited access, which may result in significant delays in processing requests

(things you discover when you implement fedramp)

Seems pretty tight for those outside of the USA. Is FAX allowed for those who live outside?

I was thinking that it may be the point. This is a service paid by Americans, for Americans, and I suspect they don't want to make it too convenient, especially for non-Americans.

From the link:

> The service will be provided at no charge, and user keys may be used to connect to any of the servers whose addresses are listed below. Additional hardware will be added in the future if the demand for the service is sufficiently great to warrant it.

Making it clear that they are going to shoulder the extra costs.

better question is will be they willing to mail you reply outside of usa.

if you really want it, there are plenty of services that provide you with virtual mailbox in usa

I wonder if they'd consider implementing NTS.

NTS uses AES-SIV and looks like it's not NIST approved and doesn't have FIPS validated implementation.

in other words - no
