June 19 (Reuters) - Retail technology and software

provider CDK Global was investigating a cyber incident and had

briefly shut all its systems down proactively, it said on

Wednesday.

The company, which provides software to car dealerships,

said its core dealer management system and digital retailing

solutions had been restored.

CDK Global added that it had tested and consulted with

external third-party experts after the incident.

"We are continuing to conduct extensive tests on all other

applications, and we will provide updates as we bring those

applications back online," the company said in an emailed

statement to Reuters.

CDK's systems first went down around 2:00 a.m. EDT (0600

GMT) and some functions began to come back online by Wednesday

afternoon, according to a report by  Bloomberg News.

The company was bought by investment firm Brookfield

Business Partners ( BBU ) in April 2022 for $6.41 billion in cash in a

deal that took private the last major publicly traded provider

of software to auto dealers and manufacturers.

Ford, General Motors ( GM ) and BMW did not

immediately respond to a Reuters request for comment sent

outside regular U.S. business hours on whether the cyber

incident had affected their dealerships.
