In coordination with other market centers, MEMX will host a test of its secondary/disaster recovery facilities on Saturday, September 26th, 2020. The scope for this weekend test will be a full feature test of all exchange functionality in order to ensure that MEMX is able to quickly relocate data center operations from Secaucus, NJ to Chicago, IL in the event that it was determined transacting exchange business in Secaucus, NJ would result in extra, unnecessary costs to investors. It is important for all MEMX customers to participate in these tests to ensure that each firm has the necessary connectivity in place to connect to the secondary datacenter if the need arises to move the MEMX primary operations to Chicago or some other location. Therefore, MEMX recommends that all firms work to participate in both this test on September 26th and the formal SIFMA/FIA BCP/DR test on October 24th to ensure connectivity in all possible scenarios.
