Customer Advisory: Event Webhook Outbound IP Ranges Changes Tuesday, May 4, 2021 from 10:00am to 5:00pm PT
Scheduled Maintenance
Report for SendGrid
Completed
Due to an unexpected issue that our engineers are investigating, we will be postponing this change until further notice.
Please do not wait until then to add the new outbound IP address ranges if you are maintaining an allow list for the Twilio SendGrid Event Webhook:
167.89.116.0/24
167.89.117.0/24
167.89.119.0/24
As a note, IP address ranges can be subject to change without notice. Unless specifically necessary, we generally DO NOT recommend allow listing IP addresses. Instead, we recommend setting up features like signed webhook requests or OAuth 2.0 for securing your Twilio SendGrid Event Webhook.
