Our provider informed us that he has to do some maintenance between 00:15 and 00:45 tonight. F-Register is obviously not available in that time slot. We appologize for any inconvenience the provider may cause.
PS: It's better to plan slightly wider time ranges, the half hour of maintenance work remains, but the start and therefore the end are postponed by the provider and now start at 11 pm - let's see when they do it at the end...
