What must you check for known Xero outages?

The status page is the correct choice because it is specifically designed to provide real-time information about the operational status of Xero's services. This page offers updates on any outages, maintenance, and performance issues that may be affecting users. By checking the status page, you can quickly determine if there are any known problems with the platform and get insights into any ongoing incidents or scheduled maintenance that could impact your accounting activities.

The other options, while they do serve useful purposes, do not offer the same level of direct and timely information regarding service outages. The help section typically contains guides and articles that may not include real-time updates. The demo company is primarily for training and exploration of the features within Xero, rather than providing operational status. Lastly, while contacting support can yield information about outages, it may not provide the immediate updates and transparency that the status page does.
