Many owners found it impossible to use their Xbox One consoles during the day. On the Xbox One subreddit, for instance, they reported seeing a black screen after their consoles booted up. Some also couldn't access saved data. Microsoft quickly responded to the situation with a tweet:
We are aware of reports of Xbox One console startup, title update and sign-in errors. We will keep everyone informed once we have more information to share. Thank you all for your patience.— Xbox Support (@XboxSupport) January 30, 2019
The company also directed users to a system status page, which then went down. It's worth pointing out that, just last week, Microsoft Office 365 users in Europe were left unable to access mailboxes for a full day, and within the past 24 hours, there was another issue impacting Microsoft users from all over the world. Cloud services including Office 365 and Azure were all experiencing trouble.
It seems users were reporting that they couldn't log into any of their accounts. It's unclear if Microsoft's Xbox One issue was related, but it did seem like an Xbox Live and software problem that made the Xbox One unusable for many customers. We suspect Xbox Live servers went down.
The issues surrounding Xbox One console startup, sign-in, title update errors, and our status page have now been resolved. Thank you for sticking with us while our teams addressed these issues and we appreciate the reports. As always, we're here and we're listening.— Xbox Support (@XboxSupport) January 30, 2019
Xbox One Users - Service changed rolled back - please reboot to confirm the issue is fixed.— Brad Rossetti (@WorkWombatman) January 30, 2019
Either way, Microsoft apparently figured out what was wrong and has fixed it. We'll keep you posted as we learn more.
