[Labs-announce] Labs-wide security updates tomorrow, 2016-06-07

[Andrew Bogott]

     Moritz and I will be applying some security patches to the 
virtualization hosts tomorrow, beginning at 14:00 UTC.  We're going to 
try to apply this change via suspend/resume cycles rather than via 
reboots -- that means that each VM should experience a minute or two (or 
three) of hesitation but should not register any reboots.

     If this goes badly and it turns out that actual reboots are needed 
I will reschedule the maintenance for a later date with more notice.  
For now, though, no action is required from any of you.
