Today was the release of the most anticipated game for an Xbox platform in a long time with Titanfall and as a result, it appears the Xbox Live servers have been limited. This has caused many gamers to not be able to find people in matchmaking for games as well as having issues just signing in.
Luckily, it appears that the matchmaking issue has been resolved, as it it no longer on the Xbox website under service alerts, but the signing in issue is still a problem for some. I was able to sign in myself, but there are plenty that are still having issues. This is of course a major issue for those that just got Titanfall as it’s online only.
Stay tuned for if any further information is released on this issue.
