Emergency Banner

Please note (7/15/19): The embed code has been updated to include the async attribute. This will allow your site to load appropriately even if the Emergency Banner is experiencing an unplanned outage.

In order to achieve coordinated emergency communications for all of Cornell’s campuses, we recommend the implementation of this web-based notification tool to complement the official university Emergency Notification System. The Emergency Banner is currently in use on over 500 websites throughout the university.

When activated, the Emergency Banner appears as a modal window that contains official statements and instructions relating to emergencies that may affect the Cornell community. The system will only be activated in the case of extreme, campus-wide emergencies or tests of the university alert system and will be disabled once the threat has been resolved.

The script for engaging the Emergency Banner is housed centrally on a CIT server and is called from each participating webpage through one line of Javascript. Because the code is not housed on local servers, there is no impact on performance when the banners are engaged.


To add the emergency banner to your Cornell University-affiliated website, please download the file or insert the following lines into the <head> section of your website. Alternatively, you can place the code just before the closing </body> tag.

  <!-- Emergency Banner -->
<script src="//" type="text/javascript" async></script>

Sites hosted using CIT's Blog Service have the emergency banner automatically enabled and do not require any additional steps for implementation.
