Fans of HBO's Game of Thrones have grown accustomed to heartbreak, but this one may have proven too much to bear. Streaming service HBO Go crashed during the Season 4 premiere on Sunday, barring many from watching the program live. HBO, a division of Time Warner Inc, said the service interruption was due to overwhelming demand and tweeted apologies to affected subscribers. This isn't the first time, though. The service also failed in March during the finale of True Detective due to volume.
