As part of our continued efforts to improve Oracle Cloud Infrastructure and Services, the Oracle Cloud Infrastructure Networking team will be performing planned maintenance on OCI Web Application Firewall (WAF). It is important that you allowlist the new, expanded subnets that are linked below (CIDR Ranges), at your origin. These IP ranges will replace the existing source ranges for requests originating from the Web Application Firewall (WAF) to your origin. Failure to allowlist these subnets at your origin before Monday March 8th, 2021 may result in an impact to any traffic/services routing requests to your origin(s) via the Web Application Firewall service.
Starting Monday March 8th, 2021 we will start the final steps to move all traffic through this expanded infrastructure.How will this affect my service?
There may be an impact on traffic/services from WAF to your origin if the subnets are not allowlisted on your end.What action do I need to take?
Configure your servers to accept connections from the CIDR ranges listed in the "Securing Your WAF" section of the following document:https://docs.oracle.com/en-us/iaas/Content/WAF/Concepts/gettingstarted.htm
