At PagerDuty we keep security and high availability at the forefront of our operations. Our cloud infrastructure provider has recently notified us that one of our outbound webhook proxies will be decommissioned soon. As a result, we will need to update the IP addresses used for delivering our outbound webhooks.
As of July 23rd 2021, we will no longer send webhooks from 18.104.22.168. In order to maintain our load balancers, a new IP address has been added: 22.214.171.124.
Please update your firewall to allow connections from 126.96.36.199 in order to continue to receive webhooks.
PagerDuty supports safelisting IP addresses, however, we do want to highlight that this method of ensuring webhook delivery security is no longer best practice. Over the last year we have added TLS 1.2 and custom headers to our webhooks which will ensure webhooks are delivered from PagerDuty. If you are migrating away from using IP Safelisting and have questions about PagerDuty’s webhook deliverability, please contact our Support team.
If you must continue to use IP Safelisting, we request you use this script to receive updates on these changes through your PagerDuty instance.
