The Dota 2 community suffered quite the setback yesterday when an entire server suddenly went offline. Last night, the game's official Twitter account said that the US East server was "offline temporarily." The culprit? A cut cable.
According to that tweet, "a cut fibre cable" was "causing a wide area outage in the hosting region." The Dota account was the only one to acknowledge the issue, although known Valve-related Twitter account Wickedplayer494 reported that both CS:GO and Team Fortress 2 had also been affected (via PCGamesN), and that players should "expect higher than usual latencies."
The US East matchmaking server cluster is offline temporarily. There is a cut fiber cable causing a wide area outage in the hosting region. In the meantime we suggest queuing in other servers.

The issues do now appear to have been fixed, which is good, but if you found yourself out of a game last night, Valve's solution wasn't exactly high-tech. The software giant told those affected that they'd just need to queue up on a different server if they wanted to play. So if you found yourself playing alongside a confused and laggy American last night, this is probably why.
