Xbox Live is currently experiencing sign-in issues and those claiming responsibility for the earlier PSN attacks, and the bomb threat against a flight carrying Sony online president John Smedley are taking credit.

Is anyone having issues with the Xbox Live Login servers?

The good news is, Microsoft is fully aware of the issue, and has this message posted on the Xbox Live status page:

Xbox members, are you having a hard time signing into Live? We’re aware of the issue and working hard to find a solution as quickly as possible. Thanks for being patient in the meantime. Please check back in a half hour for an update on our progress.

The issue does not appear to be entirely widespread. While I did have issues signing into Xbox Live with my Xbox 360, my Xbox One did not pose any problems.
