It appears as though the issue is affecting users that are both hard-wired to the internet and those that are using Wi-Fi. At the moment it is unclear what is causing the issue or if it affecting both Xbox One and Xbox 360 users, most reports are currently citing the issue as being Xbox One specific.
Microsoft's Xbox Live server status is reported to be up and running. (Update: XBL core services are down as of 4:23 PM EST).
