[Labs-announce] More to come! Labs-wide security updates tomorrow, 2016-06-08

Tue Jun 7 22:26:51 UTC 2016

This didn't go very well, and then I got pulled into a related 
emergency[1] (one that was related but largely invisible to users.)

So, I may have another go at the suspending/resuming tomorrow morning.  
As before, if we wind up needing to do something more intrusive than 
suspend/resume I will provide additional notice.

Sorry about the endless maintenance window :(
