Xero's uptime is so bad, they have disabled historical graphs
The downtime to Xero has become so bad, they actually disabled/removed the past uptime graphs/bars that let you see that their service is often having issues.
Now you can only view the 'current' status as well as any "pinned" downtime or incident that they have not currently closed. By comparison, other company's Atlassian Statuspages almost universally show past historical information.
