This doesn't seem to be a problem with cisco, but if you are synchronizing to certain NTP servers (i.e. usno or nist) they currently have reachability problems. So your cisco reports a "." that your ntp is unsynchronized. I haven't found out if the government networks are deliberately throttling traffic or if the links to the time servers are just congested. I have no idea why it started at almost exactly midnight UTC.
Where do you get that? The following certainly shows business as usual at USNO and other time sources. Some are online and other aren't. The preponderance of them are online and happy as clams. The MHSC time hosts are stratum 2 and are unreachable from each other for a reason and have always been that way. This shows that I have at least 3 stratum 1 hosts reachable via NTP. In fact, I never showed a glitch. My information also shows that WWV and WWVH never even hiccuped, I don't use GPS. LOCAL is a radio clock that needs a new antenna lashup (way down on the budgetary priority list, talk to my suits). If a Cisco router is having a problem then it is either pilot error or someone needs to be talking to Cisco. I doubt that Cisco is the problem. If you need stable time references then TIME.MHSC.NET is running at stratum 2. ---------------------------------------------------------------------------- -- ntpq> pe remote refid st t when poll reach delay offset disp ============================================================================ == LOCAL(0) .LCL. 0 l 34 64 377 0.00 0.000 10.01 tock.usno.navy. 0.0.0.0 16 u - 1024 0 0.00 0.000 16000.0 +tick.usno.navy. .USNO. 1 u 55 128 377 101.49 3.068 11.96 -tock.usno.navy. .USNO. 1 u 258 1024 377 156.88 27.304 25.67 +ntp2.usno.navy. ntp1.usno.navy. 2 u 8 128 377 101.59 -3.054 4.10 *clock.llnl.gov .WWVB. 1 u 3 128 277 37.14 -0.243 12.60 norad.arc.nasa. 0.0.0.0 16 u - 1024 0 0.00 0.000 16000.0 noc.svcs.mhsc.n 0.0.0.0 16 u - 1024 0 0.00 0.000 16000.0 condor.lvrmr.mh 0.0.0.0 16 u - 1024 0 0.00 0.000 16000.0 falcon.lvrmr.mh ntp0.usno.navy. 2 u 27d 1024 0 0.24 3.864 16000.0 raven.lvrmr.mhs falcon.lvrmr.mh 3 u 715 1024 377 0.56 -1.579 1.14 ntpq> q root@condor:/var/spool/mail Sat Jan 1 14:14:17#>ntpq ntpq> as ind assID status conf reach auth condition last_event cnt =========================================================== 1 16028 f034 yes yes ok insane reachable 3 2 16029 8000 yes no 3 16030 9494 yes yes none synchr. reachable 9 4 16031 9394 yes yes none outlyer reachable 9 5 16032 9494 yes yes none synchr. reachable 9 6 16033 9674 yes yes none sys.peer reachable 7 7 16034 8000 yes no 8 16035 c000 yes no 9 16036 c000 yes no 10 16037 c043 yes no lost reach 4 11 16038 d034 yes yes bad insane reachable 3 ntpq> q root@condor:/var/spool/mail Sat Jan 1 14:15:35#> ---------------------------------------------------------------------------- --
