The university where the EBN is hosted is having some scheduled downtime to replace the air-conditioning units. The maintainence window starts in 10 hours and is 4 hours long, so from 7am to 11am on Saturday, February 12th in the Europe/Amsterdam timezone (GMT+1 right now). I don't know how long the work will take, nor when exactly the machine will be back up (it takes a while to press the "on" button on so many machines), but it'll be down for a bit. I expect to HACF the machine early tomorrow morning, say 6:50am.
