The Diamond Light Source has been operating with users since January 2007. From the start, the cavities suffered with a high number of trips, but recently significant improvements in reliability have been achieved. We report here operational data, initially with a single cavity, and later with two installed cavities. We describe our observations during cavity conditioning and present a variety of diagnostics which were installed to identify the origin of the trips.
