[Labs-announce] Some Labs instances rebooting TODAY, 19:00 UTC

[Andrew Bogott]

Hello!

      We have discovered a surprisingly terrible bug in the kernel 
that's running on two of the nova-compute hosts.  To remedy this, we 
will be downgrading and rebooting both hosts in a few hours, at high 
noon San Francisco time, 19:00UTC.

      We will shuffle things around to so there is no impact on Tools. 
VMs on these hosts only (listed below) will experience a single reboot 
and accompanied downtime.

      Sorry for the short notice... it's worth it, believe me. We'll 
work on getting a post-mortem incident report written, but that may not 
happen until Monday.  In the meantime, here is a complete list of 
instances that will be affected:
