Eventually a botnet or two was bound to connect, see how poorly CPU mining pays, and disconnect.  :)

If it were a lab w/ 14,000 X 5 Mhash/s intel cpus even, that would be 70 Ghash/s. The linear chart shows a moderate impact to the network hashing total.

There is a 150ghash supercluster that keeps attaching and de attaching from the network. Is someone renting a supercomputer ?

Looks like admin games in some university

Why does the number of nodes drop off to zero?  It's nearly zero at the end of your snapshot, then goes to zero around noon.

There are probably network admin who use bitcoin for benchmarking, or idle time.  Bitcoin is ideal for Condor in a commercial network environment.

Fortunately, it was a false alarm.  There was a node spewing address spam.  The author of the chart has revised the data reporting, and the chart now looks like:

Because the list of "down" nodes is so easily spoofed, a better metric is simply the nodes that are active:

At any time, a snapshot of the numbers is available from:
