The cloud operations of Chinese tech giant Huawei Technologies Co crashed for 34 minutes on Monday morning, causing disruptions across a variety of services including a popular stock trading app. Huawei Cloud said that there were “abnormalities” when accessing its public cloud network in Guangzhou, capital of southern Guangdong province, according to a short statement the firm posted on Chinese microblogging site Weibo at about noon on Monday. The glitch has been fixed, but the company is still probing the cause, the statement said.

Among the clients severely affected was Tonghuashun, a stock trading and finance information app operated by Hithink Royal Flush Information Network.

These resources are managed inside data centres.
