As always, great work!

I find it odd that the diurnal blocking pattern seems to change over
time.  For example, ndnop3:24215 in Figure 1 seems completely
unaccessible at first.  A couple of days later, the diurnal pattern
seems to kick in.

On what looks like February 20 and March 15, all bridges seemed
accessible for a short amount of time from within China -- but also
LeifEricson:41213 for your control machine.  I am curious how these two
events relate?
