IS's Virtual Caliphate Struggles to Regain Footingon Social Media Jeff Seldin Islamic State media operatives appear to be flailing about in cyberspace, still trying to recover more than a week after tens of thousands of their messaging accounts were targeted by European officials. Unlike some past efforts to hamper the terror group's propaganda efforts, which dealt only temporary setbacks, the latest takedown seems to be having a lasting impact,counterterrorism officials and analysts say. "For the time being, for as far as we know, ISisnot present on the internet anymore," Eric Van DerSypt, a spokesman for the Belgian prosecutor's office, said during a news conference at The Hague last week. "We will see how fast -- if ever -- they will regain service." Only so far, the results of the operation by Europol and the European Union's Internet Referral Unit working with online service providers such as Telegram, Twitter, Google and Instagram seem to be bearing out the optimistic assessment. U.S. officials say the crackdown on Telegram, long a favorite for IS operatives and supporters, has been especially effective. .
