Google Captcha

Please see Update from Google Support Below 9.28.18
You are probably here because you recently submitted a ticket asking why this is happening in your classroom. The quick answer is Google is seeing unusual traffic from our school network that violates their Terms of Service


We believe that there are two main reasons that we are being seen as a malicious network:
1. Several computers at any time on our network may have viruses and/or malware that are causing unwanted traffic to be sent out over our network. We are working closely with our network consultants to isolate those machines and make sure they are cleaned up.
2. Malicious apps unknowingly downloaded (e.g. WhatsApp) by our users to their phones can cause unusual traffic to be sent from our network.


We have been in contact with Google directly and are following all of the standard recommendations for removing Captcha messages from pages. We are also monitoring network logs to determine when/where unusual traffic is originating from so we can isolate it.
