Depository Institution Testing (DIT) Environment

The Depository Institution Testing (DIT) environment was established to accommodate the testing and training needs of depository institutions (DIs). DIs can take advantage of the DIT to test the effect of changes in authorization, to perform contingency tests or to train new staff. The DIT also provides your institution with an environment to test application changes prior to going "live" in production.

The DIT is available for testing at the times noted below (all times are Eastern time). However, we reserve the right to pre-empt any published testing dates to accommodate special situations or emergencies that may arise.

Weekday Testing

The DIT is not available for DI testing on the first business day of each month. We will support ongoing testing starting with the second business day, which will be synchronized with the calendar date.

Saturday Testing

Applications are available in the DIT on Saturday except when internal Federal Reserve Bank testing needs arise. Changes to the Saturday test schedule will be limited to situations in which no acceptable alternatives are available.

Disruptive testing is defined as any testing that requires conditions that may interfere with normal processing. Disruptive testing includes stopped transactions, changes to normal cut-off times (third party, settlement, and secondary market close), delivery of possible duplicate messages (PDMs), Extended Recovery Facility (XRF) takeovers, Information Management System (IMS) cold starts, cash close, and GAPS reports. Disruptive testing is conducted on the following days and times (all times are Eastern time).
