Resum

Recently two blazars (PKS 2155-304 and Mrk 501) have exhibited TeV 
flaring on timescales 1-2 orders of magnitude shorter that the 
light-crossing time of the host black holes. I discuss how these 
observations challenge our current paradigm for blazar emission and 
indicate that jet instabilities are the source of the ultrafast 
variability. A model of reconnection minijets forming inside the jet 
will be presented for the blazar variability.
