Today is Leap Day, meaning that for the first time in four years, it’s February 29. That’s normally a quirky, astronomical factoid (or a very special birthday for some). But that unique calendar date broke gas station payment systems across New Zealand for much of the day.

As reported by numerous international outlets, self-serve pumps in New Zealand were unable to accept card payments due to a problem with the gas pumps’ payment processing software. The New Zealand Herald reported that the outage lasted “more than 10 hours.” This effectively shuttered some gas stations, while others had to rely on in-store payments. The outage affected suppliers, including Allied Petroleum, BP, Gull, Waitomo, and Z Energy, and has reportedly been fixed.

In-house payment solutions, such as BP fuel cards and the Waitomo app, reportedly still worked during the outage.
