Apple Network Block 

Why is there an Apple block?

The Apple network block, commonly referred to as the "Apple Block," is to prevent the speed and integrity of the school's network from being compromised by Apple devices such as MacBooks, iMacs, iPads, iPods, and iPhones automatically downloading Mac OS, iOS, or app updates. Protecting the speed of your school's network is especially important during any school wide or grade level testing such as NWEA and PARCC.

When is it in effect?

Apple Blocks are in effect 8:00 a.m. - 4:00 p.m. Monday through Friday.

Does this schedule change?

As Apple releases new iOS upgrades, the block may be 
in effect 24 hours a day for a period of time while ITS performs critical testing to ensure that no CPS systems 
will be compromised due to the upgrade.

How do I lift the Apple block?

The Apple blocks are handled by our Network Operations team and require a 48 hour advance notice to be lifted.
 
Apple Blocks are in place 8:00 a.m. - 4:00 p.m. Monday through Friday, however, a school may request Apple Blocks to be released for the latest iOS, under the following conditions:

1. Your school has been fully migrated to the new mobile device management system, Jamf.
2. The TechCo at the school contacts the Service Desk with a date range to release the block.
NOTE: The date range can not exceed three weeks
3. The Principal sends an email to the iPad Support team at ipads@cps.edu, stating the following:
  • The ticket number in subject line and in the body of the message
  • State in the email message that they take responsibility for any negative consequences to lifting the blocks
​
​NOTE: A TechCo or teacher may call in the lift request, however the Principal must follow up by sending an email to iPads@cps.edu.
