Coming just one day after massive outages took down Facebook and Instagram, another social media site was having problems on Wednesday. LinkedIn users were reporting that they too were getting an error message when they tried to log in. Tens of thousands of LinkedIn users started reporting problems around 4pm Wednesday, according to the website www.downdetector.com. They were able to log back into LinkedIn about an hour after the peak of outages. Before that though, users flooded other social media sites trying to find out what was going on with LinkedIn. Still no word today on the cause.
