      Could be but the most interesting thing is it does look like some
      fairly large sets of prefixes went away [from my vantage point ;-)]
      around the 28th.  I just added to my delta checker both classful and
      classles delta checks to help show the change. Here's what the
      trend looked like today.
      
      Date    Prefixes
      241196  40908
      251196  40844

      Here are the Deltas (Note AS174 and AS4200, if your are interested in knowing
      what went away to cause these deltas mail me directly)
