In reply to Cellinski:
From reading the above post & the first link, it appears that it was rock failure rather than anchor failure that led to Stefan Rass's terrible accident. I was witness to a similar "rock failure" at San Vito where an apparently solid hold came off injuring a bystander. I wonder if there have been other incidents like this at San Vito? My impression was that although a great destination for sport climbing, the rock is not quite as solid as some other sport venues I've been to (not that I do much sport). Maybe that's due to it being relatively "new" in terms of climbing.
Re the second point, I was under the impression that the newer bolts that are currently being placed in San Vito(e.g. by the Titt Brothers & their team) are using the same glue-in technology as used on the isle of Portland & should better resist the corrosion than the old style bolt that failed on Monte Monaco at San Vito due to corrosion.
