The numbers this time, from November 8 to November 19:
- 56 dead
- 42 open
- 10 timed out
- 9 half open
The percentage of open connections has gone down a bit from 41.6% to 36%, but they have also added measurements from a new PDP-10 at Stanford which is mostly offline. Removing that from the data set so we can compare apples to apples, things look less dire at 39% open.
