This is a message you'll see when we're working behind the scenes on fixing something with reporting, or maintenance. Typically it's not for long, however, it's hard to give a specific length of time this message will display for. It will depend on how long the fix/maintenance takes

If it's something simple we're able to fix/maintain during the day, this message will appear, however - if it's more in depth, we will try and fix during the off hours.
