The precise numbers will vary depending where your BGP view is in the
worldwide Internet.  You are correct.  There was a steady decline in
both number of prefixes and number of asns in the 24 hours before
Midnight.  The global routing table shrunk by 1000 routes before the
hour before Midnight EST.  In that hour, another 600 routes withdrew.
The routes remained stable at that level for 5 hours, and then began
to climb back to normal levels.  About 30 ASNs vanished prior to the
rollover.

>From my view, the decline actually started on December 24. But it isn't
really noticable until the last 24 hours.  Since the graph of practically
anything about Internet always shows an increase, a decrease is an
interesting change.
