Reminder that these outages happen, one tomorrow, and the next on friday.  Ideally you should only notice jobs in the system seem to be running longer than they would have if they were running while the outage happens.

To quote:  "There is 345kV high voltage equipment that needs repair which is going to require the lab move from Master Substation to Kautz Road Substation on two occasions. Computing will be powered down in GCC computer rooms A, B, and C during both of these scheduled outages."

For CMS the outage will only affect CPU resources.  Jobs running during the outage will die and be rescheduled.  You should not see job failures (for this reason at least), but may see that jobs running during this time take longer because of the restart.
