After we were tipped about "essential maintenance work" being conducted in Europe on the PSN, we contacted Sony to find out if North America would be shutting down for a time as well. Turns out, it is. The PSN is scheduled to be unavailable tomorrow, Oct. 14, during the following time:
11AM - 4PM Pacific
2PM - 7PM Eastern
Be sure to plan accordingly and get those petitions ready demanding a refund for the downtime.
