Impact No impact to WSS traffic is expected during the maintenance window.

Required Action prior to February 15, 2022 Failure to make these changes could prevent users from connecting to WSS, accessing third party web applications, or authenticating against the service using the Auth Connector (where applicable).

• Firewall rules regulating connectivity to/from your network to WSS should be adjusted to allow traffic to pass to the IP network listed above. • Third party applications that regulate connections by source IP address should be updated to accept connections from the new egress IP networks listed above to ensure traffic proxied through WSS can reach the application. • Auth Connector must be able to communicate with all egress ranges listed above on TCP 443, where applicable.
