01 The Hour
20:00
Tuesday 23 June 2026, United Kingdom
From around eight in the evening the monitoring site Downdetector logged more than a thousand reports of payment problems at one supermarket chain alone. Answering a customer, the chain said there was an issue with Worldpay affecting it and other businesses taking card payments.
The processor's own notice named the cause: a third-party power disruption, causing intermittent transaction authorisation issues and tokenisation request errors on some of its platforms. Service had been restored to some of them and the teams were still working. England were playing Ghana. The pubs were full.
02 The Sequence
23 Jun Tuesday evening. Tills and contactless terminals begin failing. Downdetector logs more than 1,000 reports of payment problems at Tesco from around 8pm. Customers report being unable to pay by card at a number of retailers.
23 Jun Tuesday evening. The company posts a notice on its website: a third-party power disruption is causing intermittent transaction authorisation issues and tokenisation request errors on some Worldpay platforms, technical teams have restored service to some platforms and continue to troubleshoot to restore full service as soon as possible.
23 Jun Tuesday evening. Videos circulating on social media show queues at cash machines. Several pubs and entertainment venues post notices that they are taking cash only until the system comes back.
23 Jun Tuesday evening, second notice. A technical issue has caused a one-day funding delay for a subset of merchants on the Worldpay Total platform, and technical resources are working to process the affected files. This is a different fault from the one at the terminals.
23 Jun Later that night. Service is restored to some platforms within hours. Tesco says the issue that affected payments in store and online is now resolved.
24 Jun Wednesday morning, New York time. The status page records the funding and payouts issue resolved. Customers scheduled to receive funding on 24 June will receive funds on 25 June, one day later than expected according to the customer funding cycle.
24 Jun Wednesday. Worldpay and Global Payments state that a small subset of merchants on the Worldpay Total platform will receive their funds one day later than expected, due to a technical issue stemming from a UK Power Networks disruption that has already been resolved. The number of customers affected is not released.
24 Jun Wednesday. A spokesperson says the United Kingdom experienced a power grid disruption which caused intermittent transaction authorisation issues for some Worldpay clients, that restoration was completed the previous day, and that transaction authorisations are processing normally.
24 Jun Wednesday. The outage falls in the middle of a corporate transition: Global Payments had recently closed a 24 billion dollar acquisition of Worldpay.
03 The Hidden Dependency
Two things broke that evening, and only one of them was visible in the pub.
Authorisation is the message that says the card will be honoured, and it failed intermittently for several hours. Funding and payouts is the separate leg that moves the takings to the merchant's own account, and that one was still being worked on after the terminals came back, with files to process before anyone was paid.
A merchant on that platform could have working terminals again by closing time and still be a day late on the money, and the notice that said so was a different notice from the one about card acceptance.
Underneath both sat a power network that the processor does not own.
04 What Still Worked
The Cash Machines
They kept dispensing, and the queues moved to them. Videos circulating that evening showed lines at cash machines while venues put up cash-only notices.
The Platforms Not Hit
The notices are careful about scope: authorisation issues on some Worldpay platforms, service restored to some platforms first, and the funding delay confined to a subset of merchants on one named platform.
The Funding Cycle
It held its shape while slipping a day. Merchants due funding on 24 June were told they would be paid on 25 June, according to their own funding cycle.
05 The Document
The Document 24 Jun 2026
An incident record on a status page, filed under Funding and Payouts rather than under card acceptance. Its resolution text does the work of the whole episode: the technical issue is resolved, and some customers scheduled to receive funding on 24 June will receive funds on 25 June, one day later than expected according to the customer funding cycle. No number of affected merchants appears. The earlier entry in the same incident says only that technical resources are working to process the affected files.
06 The Pattern Library
1
When one retail withdrawal channel closes or fails, demand concentrates on whichever channel is left open, and the capacity of that channel sets what a depositor can obtain.
Observed: Northern Rock 2007, Cyprus 2013, India 2016, Greece 2015, United States 1933, Argentina 2001, Lebanon 2019, Worldpay 2026.
2
A currency replacement can require physical modification of each cash dispensing machine before the new notes can be issued, so the machine estate returns to service site by site rather than at once.
Observed: India 2016.
3
Withdrawal limits imposed on a domestic banking system can be written to exempt cards issued outside it, so one machine dispenses under two rules according to where the card was issued.
Observed: Greece 2015.
4
Domestic payment and deposit channels can continue operating while cross-border payment routes fail, with the central bank standing in as the intermediary for payments to and from the country.
Observed: Iceland 2008.
5
When the institutions that convert payment instruments into cash are closed, wages and checks already received cannot be spent, and merchants and carriers extend their own credit in place of the missing conversion.
Observed: United States 1933.
6
A public employer short of the national currency can pay wages in an instrument it issues itself, which then circulates alongside the currency it stands in for.
Observed: Argentina 2001.
7
Withdrawal restrictions can be imposed by individual institutions and their trade association rather than by statute, so the limit differs from bank to bank and no law governs it.
Observed: Lebanon 2019.
8
A cash withdrawal ceiling set in nominal units has to be raised alongside the note denominations that pay it, because the ceiling can only be dispensed in the notes that exist.
Observed: Zimbabwe 2008.
9
A payment outage can hit card authorisation and merchant funding as separate faults, so acceptance at the terminal is restored while the money owed to the merchant arrives a day late under its own incident notice.
Observed: Worldpay 2026.
Changed today: Entry 1 gained Worldpay 2026, where card authorisation failed for several hours and the queues moved to the cash machines while venues took cash only. Entry 9 added, on authorisation and merchant funding failing as separate rails under separate notices.
