The website DownDectector recorded growing outages in services at Visa, ADT security and Amazon, and airlines including United, American, Delta and Allegiant had all been grounded.
Microsoft 365 posted on X that the company was “working on rerouting the impacted traffic to alternate systems to alleviate impact in a more expedient fashion” and that they were “observing a positive trend in service availability.” Airlines, railways and television stations in the United Kingdom were being disrupted by the computer issues. The budget airline Ryanair, train operators TransPennine Express and Govia Thameslink Railway, as well as broadcaster Sky News are among those affected.
Several airlines made statements on X saying that they were following manual check-in and boarding processes and warned of delays due to technical problems.
