 Who notified Dumbledore about the change in trial date?

1.  Percy 
 
2.  One of the Aurors who works for the Order could have seen Arthur 
and Harry rushing off to the trial
 
3.  Maybe Arthur had time to contact Dumbledore himself, after he 
sends Harry into the courtroom alone.
 
4.  Possibly some of the portraits of former Headmasters could have 
been keeping an eye on Harry at the MoM 

EXCELLENT points, all of them.  I never considered anyone but Percy 
or Shacklebolt, and I had a hard time crediting Shacklebolt because 
he wouldn't have known beforehand (but he was in the office that 
morning; we saw him speaking w/ Harry and Arthur, so he could have 
seen them, got Dumbledore right away etc.)
Hickengruendler adds there is a portrait of a former headmaster near 
the DoM, right by where the trial takes place.
I actually like the idea of Arthur doing it but wonder if he sat 
right outside the courtroom the whole time.  The portrait makes a lot 
of sense, as does Grey Wolf's idea that it could have been Marchbanks 
or Ogden (although I don't agree that the time and place change was 
a "minor" matter at all).
I don't think we could cite Dumbledore's notification as evidence 
that Percy is acting as spy, because of the clear possibility that 
there are so many others who could have done this job.  Which brings 
me to another point: it seems Dumbledore has eyes and ears all over 
the Ministry already.  If Percy was doing something undercover, what 
else could it be?  It makes me think about what Arthur is up to (oh, 
am I bringing that up again?) -- there are Unspeakables, there are 
Aurors, there's the Order -- and Arthur has been doing something that 
predates the Order and is critical to Dumbledore.  I just don't know 
what.
