Total reset

Sunday 3/25 4 pm till midnight:

 6 router resets with IP changes

Mionday 3/26 6am till midnight:

 19 router resets with IP changes

This is worse than I thought it was by far.  The good news is that aside from the one at 6AM to start the day that could have been any time last night, it has been nearly three hours with no further router resets. 

Can anyone from AT&T comment as to whether this is normal behavior or symptomatic of an overcrowded DSL circuit?
