\subsection{Beam-unrelated}   Of course some failures do not affect the beam, but they do affect the user experiments.   Those If the beam is stored and all beam parameters are within the desired limits, there still  can be failures of the infrastructure problems that prevent most users from running any experiments. Infrastructure outages  like a massive  control system failures, insertion device failures, etc. failures or photon shutter interlocks can lead to those situations.  There cannot be a simple rule to calculate the start and stop of these types of event; but they should be recorded if they have an influence on a significant number of the experiments.
