The reason is that the receiver stopped tracking without any obvious reason around 6:00 UT that day. The problem is under investigation, but at this moment it is unclear what the root cause may be. The receiver reports that it is unable to lock on any satellite. If it turns out that the antenna or the receiver itself is at fault, we will need to ship replacement equipment. At this moment, we do not have a spare receiver available. This could mean that the outage may last for a couple of weeks. We will try to return the station back in operation as soon as possible. Of course, we regret this situation and we apologize for the inconvenience it may cause. Boudewijn and Danny
