Sample entries

Part 01
The opening moment, on the clock, and what was happening.
01The Hour
Saturday, mid-morning.
Sample: Cyprus, 2013
The announcement had been made overnight and the branches were shut for the weekend anyway. The machines still worked.
Part 02
The reconstruction: hour four, day two, week three. Every step carries a date, and where accounts differ, the issue says so.
02The Sequence
The announcement is made.
The machines still work.
The cash machines keep dispensing, on limits.
Part 03
The dependency that turned out to matter, and was less visible than the headline failure.
03The Hidden Dependency
The cash machines kept dispensing, on limits, for days after the announcement, while electronic transfers between banks had already been stopped.
The failure was not that the money vanished. It was that some rails carried on and others did not.
Part 04
The channels that kept working longer than the rest.
04What Still Worked
Cash machines
Kept dispensing, on limits, for days after the announcement.
Card network
Continued to operate while card acceptance at merchants weakened.
