[FINAL UPDATE] A Microsoft representative provided GameSpot the following comment on the recent Xbox Live issues. You can read the full statement below.
"Microsoft is investigating an issue that may interrupt customer access to some Microsoft online services. This is unrelated to the launch of Titanfall and the Xbox Live service is up and running. The issue on Xbox is resolved, but unfortunately a small percentage of Xbox One owners may still experience a sign-in issue on Xbox Live, which can be fixed with a cold reboot of the Xbox One by powering down, unplugging, waiting 10 seconds, plugging back in and powering back on. The Xbox team sincerely apologizes for the interruption.
[UPDATE] Respawn Entertainment cofounder Vince Zampella tweeted about the Xbox Live outage just moments ago.
[UPDATE 2] Titanfall and Forza 5 matchmaking on Xbox One are now back in working order, according to the Xbox Live Service Status page. However, the page points out that Xbox Live itself is still inaccessible for some users.
"Are you having difficulties signing in to Xbox Live? We are currently engaged and our team is hard at work to get you back online," Microsoft said. "Thanks for your patience while we get this fixed. We'll update you again in 30 minutes."
[UPDATE 3] Xbox Live director of programming Larry "Major Nelson" Hryb says the Xbox Live issues are unrelated to Titanfall.
The original story is below.
The launch of Respawn Entertainment's much-anticipated multiplayer shooter Titanfall has not gone off without a hitch. The Xbox Live Service Status page currently states that Xbox Live is currently struggling to get players into matches of Titanfall as well as Forza Motorsport 5.
A second issue is also preventing some Xbox Live users on Xbox One from being able to sign in altogether. Microsoft said it is aware of both issues and is "investigating" the problems right now. A status update will be provided in 30 minutes, Microsoft said.
Xbox Live for Xbox 360 is currently up and running normally.
In the case of Titanfall, Respawn engineer Jon Shiring said in an interview yesterday with Engadget that any server issues that occur for the new game are on Microsoft to fix. This is because the game relies so heavily upon Microsoft's Azure cloud servers.
"One of the really nice things about it is that it isn't my problem, right?" Shiring said. "We just say [to Microsoft], here are our estimates, aim for more than that, plan for problems and make sure there are more than enough servers available--they'll know the whole time that they need to bring more servers online."
Titanfall requires an Internet connection to play, meaning every single copy of the game in the wild today is tapping into the network. For more on Titanfall, check out GameSpot's review.
