Roughly from last night (5:00UTC [10pmPT]), EY has been steadily increasing in dust levels (and obviously alarming constantly the whole time).  0.3um counts are over 10,000.  No other VEAs are seeing an increase in dust like this building.  I don't see a temperature increase.  Could a door be open?  HVAC issue?  Something burning?
