I totally panicked when I tried something interesting with a heading link in a document and all of Confluence crashed with this message: > This site is currently undergoing maintenance. We apologize for the inconvenience. Augh! Fear! Panic! So there's a scheduled upgrade underway, and it's not my fault for trying to link to a heading with a contraction in it after all. Hooray. Can our Confluence host clarify this text to say (for example) "planned maintenance" when it's an intentional outage?
