For the second time in less than a month, Microsoft's online service for the Xbox 360 appears to be experiencing problems affecting a broad swath of users.
Here's what the official Xbox Live status page says:
Members will experience difficulties attempting to login to Xbox LIVE. Our engineers are hard at work to find and implement a fix as quickly as possible. Keep checking back with us every 30 minutes for an updated message and thank you for your patience.
Kotaku will be checking on the status of the service and update this post as needed.
