While it’s to be expected that average sites will be hit by hackers from time to time, the thought of Steam going down seemed practically inconceivable. After all, it’s the world’s largest digital storefront, a social hub and online game platform all in one. But after years of running without much in the ways of unplanned downtime, Steam is currently inaccessible and all signs point to a DDoS attack.

A DDoS, short for “denial-of-service,” attack is not hack but instead an attempt to bring a website down by overloading it with communication requests. EA’s competing service Origin experienced one of these outages earlier in the day.

While we can’t confirm at this point that a DDoS attack has actually taken place, the site has been either down — or intermittently working — for the past half our or so and a group has taken responsibility for the attack.

We’ll follow the story and keep you updated. In the meantime, head over here to check the current status of Steam services.
