The company said the outage was caused by a third-party technology provider and was not a cybersecurity issue. It started around 12 a.m. during a configuration change and was close to being resolved about 12 hours later, the Chicago-based company said.
The company said the outage also wasn't related to its shift to Google Cloud as a technology provider. In December, McDonald's announced a multi-year partnership with Google that will move restaurant computations from servers into the cloud. The partnership is designed to speed up tasks like ordering at kiosks and to help managers optimize staffing.
At another location in Thailand’s capital, there was plywood over a door with a sign saying, “Technicians are updating the system," even as customers were ordering again and paying digitally.
