Updating Plugin for WPMUDev dashboard

I recently tried to update the wpmudev dashboard on one of my sites and received the following message:-

Disabling Maintenance mode…

I am somewhat confused as this appears to be the path to a local folder rather than online. In fact I have had a similar problem with other updates for other plugins. I wonder if you can shed any light on this for me.

Thanks
