Self-Pay Gas Station Pumps Break Across NZ As Software Can't Handle Leap Day (arstechnica.com) 92

Posted by BeauHD from the leap-year-glitch dept.
An anonymous reader quotes a report from Ars Technica: 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. A representative for Petroleum, when prompted via Facebook to "maybe remember Leap Day in four years' time," responded: "We'll add it to our Outlook reminders :("

  • Maybe the NZ Government will think about regulating such a monopoly provider of an essential service so they are either reliable or not a monopoly.

    • What fraction of gas stations were affected? 1%? 25%? 95%?

      • Article says one of the affected suppliers is Z Energy, and according to Invenco [invenco.com], Z Energy alone represents "around 45 per cent of New Zealand's total fuel needs."

        So... a lot of people were affected by this.

            But theres a lot of retail competition here - where I live, a modest town of 22,000 people, there are 2 Z fuel stations, 2 BP fuel stations, 1 Challenge fuel station, 1 Mobil fuel station and a Waitomo fuel station.

            Travel 20 minutes up the road to the nearest city, and you can find 50 fuel stations covering a population of 185,000, of which only 8 are Z Energy fuel stations.

      Normally Id agree with you, but NZ governments arent great with regulation.

      We are a country of 6 million trying to act like a country of 25 million, so we want nice things while not having the import market of the size to be as cheap as elsewhere.

      For example, until recently, there was one supplier of bitumen products covering 70% of the NZ market, and all bitumen is imported here. The NZ transport agency didnt like having to pay a foreign company rates higher than other countries so it had legislation passed to make the transport agency the sole supplier and required importers to sell to it at a fixed price, much below the then current market rate.

      The 70% holder of the market basically overnight went “yeah, fuck no, bye” and pulled out of the market rather than sell to the government at something at or below cost. It stopped importing the product entirely.

      So now theres a massive shortage of basic roadbuilding materials, and no new companies filling the hole because why the fuck would they?

    • Maybe just go to a fuel station that accepts cash. Since the only effect is the payment processor it is not a massive issue.

    • A small outage once in 4 years affecting less than half of companies involved which in most cases had a work around (not being able to pay at the pump doesn't mean not being able to buy fuel since it still worked inside), is not something the NZ government will given the tiniest shit about.

      I mostly use cards for the points, I don't really care if they track my purchases. But I always make a point of having some cash on hand for cases when cards don't work, not a huge amount that it would hurt to lose or be stolen, but enough to pay for a dinner or some gas. Sometimes use it for tips as well, when I'm not sure who tipping on a card may actually go to. Backups are not just for files.

      • Paying tips in cash doesn't mean it's all going to your server unless they're pocketing the tip which at most places would probably get them fired. Most service industry places i've known of usually pool the tips of everyone on the shift then at end of shift the whole tip bucket gets evenly distributed between all the servers / bartenders that worked that shift and bar backs / bussers getting some fraction of the tips as well.

          That would be fine so long as all those people have access to all the card transactions and know exactly how much in total is to be split between them. Some unscrupulous owners skim some of that off for themselves as well though, and how would the workers know? Sorry, I'm tipping the help, not the management. Cash adds a bit more transparency, but I never said it was perfect.

        • It actually is pretty transparent to them, Of the places I am familiar with it's usually one of the servers that counts out the drawer at the end of the shift. You start shift with $2000 in the money bag to start out the register. During shift you're putting cash transactions into the register and entering card receipts into the register as they happen, during a slow period or end of shift. End of shift you run a report register says you made $5000 in sales and whatever in card trips. Put that $2000 start

        • Sharing tips like this pretty rare.

    • Paying cash for gas is annoying in this pay before you pump world. Go in hand the clerk $60. Pump and you can only fit $55 worth into your tank so now have to go back in and get the change. It wasn't that long ago that you could pull up to the pump and just immediately start pumping then when you were done you would go in and pay whatever the total came out to be. Then gas prices skyrocketed and drive offs became so common that they ended the ability to do this.
