On the early morning of 7/24/2017 starting at 12:30AM CDT we will be
doing OS upgrades on the storage system (znas4) that some of our virtual
machine hosting is stored on. 

Also, on the early morning of 7/31/2017 starting at 12:30AM CDT we
will be doing OS upgrades on another (znas2) of the storage system
that some more of our virtual machine hosting is stored on.

We anticipate no problems moving to the version of code that is planned,
a 3rd storage system (znas3) has been running this version of code for a
while now.

The systems are fully HA clusters, so downtime won't be needed to do
the upgrades, and the upgrade process has gone pretty smoothly in the
past (besides one bug triggered that has since been fixed). These
systems only hold virtual servers and no other services here.

Upgrades are required for some minor bugs, better performance, current
compatibility, etc. 

We'll be monitoring everything as we normally do. If you have any
questions please let us know at [log in to unmask]

Thank you.
