Where are you located?

I'm in Silicon Valley.

Both of my TBolts went into holdover about 0:15 UTC and stayed there until 
2:15.  One recovered enough to reset the counter about half way through.

I have crappy antennas so holdover is common.  It's been good weather 
recently so long outages are a bit strange.  (I think wet weather reduces the 
signal getting through my roof but I don't have good data to back that up.)

Both of my TBolts had huge PPS Offset for several minutes about 2:00 UTC.  
One was 8000022.50, the other was 6999996.50 for 9 samples at 64 second 
spacing.

Both units reported the a0 and a1 parameters changing, one at 2:01, the other at 3:41
  a0=0, a1=1.77636e-15
The 0 is strange, but I've seen it before.
