Jagger 3 Winding Down

Matt Cutts says that the Google Jagger update is winding down:

As Jagger1 and Jagger2 wind down and Jagger3 is visible at 66.102.9.104, I wanted to recap where things stand.

• Jagger1
  was visible at most data centers starting around 10/16/05. A second,
  refreshed version of Jagger1 was visible recently at 66.102.7.104 and
  was at all data centers by 11/7/05.
• Jagger2 was visible starting at 66.102.9.104 starting around 10/27/05. Jagger2 was visible at all data centers by 11/6/05.
• Jagger3
  was visible starting at 66.102.9.104 around 11/4/2005. Jagger3 is not
  widely visible yet (it might also be at 216.239.51.104), but I expect
  it migrate to other data centers over time.

Q: Is the update winding down?
A: It’s starting to. Recall that all of Jagger1/2/3 are separate
changes. Jagger1 and 2 are done, and you can see what Jagger3 will look
like at 66.102.9.104.

My one take-away from Jagger has to do with the Sandbox - I’m seeing sites coming out in record numbers…
