Transition to New SIP Production IP Addresses

The MSO and Perspecta began preparing to transition the USAccess system to new IP addresses as part of planned infrastructure work. GSA is updating these addresses for most of the service, however there is an action needed by Agencies if they use the USAccess SIP service. The SIP Test and Staging IP addresses were transitioned on June 28 and SIP Production IP addresses will transition on August 3.  


Agencies using the SIP service must add these new SIP IP addresses to their Agency IT infrastructure in order to avoid issues using the service. If Agencies DO NOT utilize the USAccess SIP service, no action is required. 

NOTE: During the August 3 transition maintenance windows, the SIP service may not be available as the IP addresses propagate. Role holders may experience intermittent issues using the other USAccess Service portals. If you experience issues, please log off and try to access the Service portals again later.
