In addition to Nasdaq's participation in the SIFMA DR test on October 24th, Nasdaq will operate the Nasdaq PSX exchange out of the Chicago data center as the primary matching engine during the week of October 26 through October 30. During this time all Nasdaq PSX features and functionality will be available. Nasdaq PSX operations will return to the Carteret data center on Monday, November 2, 2020. Operating PSX out of the Chicago site will allow firms to gain additional confidence that they can react quickly in the event that Nasdaq decides to move the operation of all its market centers to its Chicago data center.

Additionally, as announced in ERA2020-3 and ETA2020-67, Nasdaq will participate in the SIFMA DR test on October 24. During the test, all Nasdaq markets will be running out of the Chicago data center. All markets other than PSX will return to normal operation out of the Carteret Nasdaq data center on Monday, October 26. Chicago will remain the primary data center for PSX on Monday, October 26. For more information on connecting to PSX while it is operating out of the Chicago data center, please see the FAQs here.
