(b) Delay by a collecting bank or payor bank beyond time limits prescribed or permitted by this [Act] or by instructions is excused if (i) the delay is caused by interruption of communication or computer facilities, suspension of payments by another bank, war, emergency conditions, failure of equipment, or other circumstances beyond the control of the bank , and (ii) the bank exercises such diligence as the circumstances require.
