Jonathan Mayer, a PhD candidate in computer science & law lecturer at Stanford University, said that Mrs Clinton may have told her Internet service provider that she was starting a small business to allow her to set up the server.
He said that Internet companies like Time Warner are wary about allowing individuals to do so as they might be hackers looking to send spam.
Mr Mayer added that after carrying out his own tests it appears that Mrs Clinton’s server is still up and running, despite the ongoing row.
He told Dailymail.com that it ‘does appear that it’s the same server, though I cannot be sure’.
