Microsoft Corp's LinkedIn said that its app and website were functional after a brief interruption on Wednesday.
Earlier in the day, nearly 15,000 users had reported issues with the social networking service, according to Downdetector.
Downdetector tracks outages by collating status reports from a number of sources including user-submitted errors on its platform. The outage may have affected a larger number of users.
A majority of users across the United States, however, reported that they had issues accessing LinkedIn's website.
