Xi'an big data bureau head Liu Jun was suspended from duty for poor performance after the health code system crashed twice amid city-wide COVID-19 screening in the capital of Shaanxi Province, the local authorities said on Wednesday.
Another official Liu Xin was appointed as candidate for deputy chief of the bureau to preside over related works.
The system crashed twice as the city faces a resurgence of COVID-19 cases,
which caused inconvenience for residents, triggering wide attention among Chinese netizens.
At 9 am Tuesday, Xi'an started a new round of city-wide nucleic acid testing,
but many local residents found that the health code system wasn't working.
They needed to have their QR code scanned before they underwent nucleic acid testing.
The big data bureau told the media that the traffic volume of the platform was too large.
At around 10:30 am, the system started to work again.
On December 20, the system crashed for nearly a whole day.
Many residents could not take public transport or receive a nucleic acid test because they needed to scan the QR code before conducting such activities.
