A survey on failure analysis in 2008 for nine light sources~\footnote{Survey participants for the failure analysis questionnaire came from: APS, ESRF, SPring-8, Diamond, SOLEIL, BESSY II, Elettra, ANKA and SLS.} revealed significant differences for the calculation of beam availability~\cite{L_deke_2009}.
In the following we summarise the main findings of the survey.
In many cases the beam availability calculations were determined by identifying events as ``downtime'' that interrupted
data taking for the majority of the users.
Some facilities considered ``long'' injector outages - causing ``decaying beam'' operation - to be downtime, others accounted for these events individually.
Most facilities only counted beam delivery between two outages if it exceeded a minimum duration.
The minimal required duration varied between 15 and 60 minutes.
...
If a particular failure mode is identified to be more frequent at some facilities,
then this provides an incentive for a common project to develop more reliable solutions.
As a consequence of everyone using the same common metrics, a fairer comparison may also
emerge when requesting funding
to from supranational authorities.
