As part of our ongoing efforts to improve the Indigo platform and cloud server infrastructure, we will be adding an additional application gateway server in front of the Indigo application to include extra protection and to manage better the Indigo Suite applications traffic. 

On 1 May 2020, we are changing the application server inbound IP address to 40.114.191.108. We have scheduled this maintenance for a time when traffic is typically at its lowest and we apologize in advance for any inconvenience. If you have any questions or need assistance, please contact us.
