[outages] Fwd: NTP Issues Today

[Jeremy Chadwick]

Quite scary, for the following reason:

$ ntpq -c peers tick.usno.navy.mil
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*REFCLK(45,0)    .IRIG.           0 l    9   16  377    0.000   -0.001   0.001
+REFCLK(45,1)    .IRIG.           0 l    8   16  377    0.000   -0.006   0.001
+10.1.4.40       .IRIG.           1 u   22   64  377    0.146    0.024   0.013
-10.1.4.51       0.0.0.0          2 u   48   64  377    1.516   -0.228   0.301

$ ntpq -c peers tock.usno.navy.mil
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*REFCLK(45,0)    .IRIG.           0 l    3   16  377    0.000   -0.001   0.000
+REFCLK(45,1)    .IRIG.           0 l    2   16  377    0.000   -0.007   0.000
+10.1.4.40       .IRIG.           1 u    6   64  377    0.116    0.029   0.017
-10.1.4.51       0.0.0.0          2 u   65   64  377    1.467    0.080   0.182

Note that both of their servers prefer to sync off of local hardware
time devices (specifically dedicated hardware with IRIG/AFNOR TCRs in
them).

I'd love if one of their admins could explain what happened, for
educational benefit at bare minimum.
