FAQs
| Q: Why is DE retiring Canadian-hosted environments (like www.discoveryeducation.ca)? |
A: As we prepare for the 2026–27 school year, Discovery Education is moving to a single-hosted environment for U.S. and Canadian partners to deliver a more consistent experience. After this transition, data will be stored in the U.S. with safeguards in place. Your products, pricing, and contract terms remain unchanged.
What do I need to do?
- Set up new login and rostering at DiscoveryEducation.com before the school year starts. Contact education_info@discoveryed.com to begin.
- Export any needed data by July 17, 2026 or reach out to our Customer Support Team by September 30, 2026.
| Existing data in the Canadian environment will be permanently deleted on September 30, 2026. It will not be recoverable. |
| Q: Why would I need to adjust my firewall exceptions? |
A: A Firewall does an acceptable job of protecting your computer against many backdoor communication attempts. Many applications that require a firewall exception to be added will do so automatically during installation; however, sometimes you will have to manually allow an application to have access to the internet.
| Q: What is caching? |
A: Caching is the technique of storing frequently visited information in a location close to the requester. A Web cache stores Web pages and content on a storage device that is physically or logically closer to the user, which is closer and faster than a Web lookup. By reducing the amount of traffic on overburdened Web servers, caching provides significant benefits to ISPs, enterprise networks, and end users. Our site is dynamic and to maximize its use, we strongly recommend that it is excluded from any existing caching device.
