Summary
When several students are using the coding tutorials in the Hour of Code section on code.org, Internet access seems to slow down. This article explains how to fix this.
Problem
When several students at once (about 15-20) are using the coding tutorials in the Hour of Code section on code.org, an element of the site will trigger several processes of the filtering engine. This can cause Internet access to slow down for everyone.
Solution
The solution to this problem is to whitelist the element causing the problem, so it does not get caught in the filtering engine.
You need to create a filtering policy to whitelist the site bam.nr-data.net for everyone, and this rule needs to be placed at the top of the filtering policy table. For further information about creating filtering policies, please visit this page.
