On April 15, 2011, the U.S. Attorney's Office for the Southern District of New York seized and shut down Pokerstars and several of its competitors' sites, alleging that the sites were violating federal bank fraud and money laundering laws.
The causes for PokerStars lag issues may be split into 3 major categories: Platform server problems (when it's not you, it's them) Device issues - software conflicts (with security / firewall software), out-of-date PokerStars app.
