Yep.

We are required by FINRA to verify that our clocks on our trading systems are within a certain tolerance of NIST time. We are still seeing issues with 3 of the NIST servers this morning. Since NIST is on a skeleton crew anyway due to the government shutdown, I don't expect any resolution shortly.

Looks like most time.nist.gov servers (3 x NIST sites on AS49) are single homed on CenturyLink, anyone noticed NTP issues yesterday?
