Saving Your Network Data

There are many factors that affect load times for CodeHS, including your schools’ network settings. CodeHS support might ask you to save your network data so our engineers can analyze the specifics of your experience.

Here’s how to save your network’s data for us to inspect, in Chrome, and Firefox:

Google Chrome

1. Navigate to the CodeHS page where the problem is occurring

2. In the top menu bar of Chrome, select View->Developer->Developer Tools. This opens a console of developer tools that give additional data about browsing.

3. From the bottom panel, select Network.

4. Press the Record button in the top left of the Network tab to enable recording. If it’s red, it is recording.

5. Check the box to Preserve log.

6. Refresh the page and reproduce whatever actions were slow.

7. After you’re finished, right click anywhere on the list of requests in the network tab, select Save as HAR with Content, and save the file to your computer.

8. Email your .har file to the email address we provide.
