San Francisco: US chipmaker Nvidia has confirmed that it is investigating a cyber incident that has reportedly downed the company's developer tools and email systems. Nvidia told 'TechCrunch' that the nature and scope of the incident are still being evaluated, adding that the company's commercial activities have not been impacted as a result. "We are investigating an incident. Our business and commercial activities continue uninterrupted. We are still working to evaluate the nature and scope of the event and don't have any additional information to share at this time," the company was quoted as saying. While Nvidia is not sharing any more details about the incident, The Telegraph reports that the company's email systems and developer tools have been suffering from outages over the last two days following a "malicious network intrusion", the report said.

The company said the decision was mutual, resulting from "significant regulatory challenges preventing the consummation of the transaction, despite good faith efforts by the parties".
