Airplane Mode Test Downtime on March 13

What you need to know

On-call team members will not have remote IT network access during the network-wide "Airplane Mode" system downtime on Sunday, March 13 from 10 p.m. to 11:59 p.m.

If you are a team member on-call during this time, you will NOT have network remote access, and will only be able to provide support while onsite within the HMH network.
