Saturday Testing
Applications are available in the DIT/DIT2 environments on the scheduled Saturdays, as published. These testing dates are subject to change at any time should an internal Federal Reserve Bank need arise. To ensure testing needs are met and proper communication is received regarding changes, a Test Request Form must be filled out five days prior to the scheduled test. If there are no test requests for a given Saturday, the DIT/DIT2 environments will be closed on Friday. The cycle date for Saturday testing will be the continuation of the previous business day.
