Steam is suffering from connectivity issues, and attempts to use various aspects of Valve's online service return "118" errors, which say: "Unable to connect to server. Server may be offline or you may not be connected to the internet." Shacknews notes a pair of twitter users are claiming to be behind the Steam outage, but Valve has not yet officially responded to the situation. Likewise, Polygon notes hacking group DERP is taking responsibility/credit for knocking EA's Origin offline with a distributed denial of service attack, but this seems to have ended, as EA tweets that Origin is back online, while Steam is still having problems as of this writing.
