Dear colleague,
The computing center in NIST Gaithersburg will be shutdown for maintenance next weekend, and the time servers there (IP 129.6.15.x) will not be available from approximately Noon Eastern time (16 UTC) on Friday, 20 October to about Noon Eastern time (16 UTC) on Sunday, 22 October. The exact times may be slightly different. I hope that the service will be restored earlier on Sunday morning.
The servers at the other locations will not be affected.
