Akvopedia was unreachable from 10:35 to 13:24 today (2015-01-09) due to a silly mixup.
Port 80 needed to be closed on a completely different server (which happened to be right next to Akvopedia in the control panel) and Akvopedia's was mistakingly.
The expected notification about an http service becoming unreachable was sent but failed to notice that the message concerned the wrong server so the port remained closed for 3 hours.
