Metric numbers never really tell the true story.
I was looking into FTS transfer failures for the ATLAS experiment; (transfers involving ATLAS; I wasn't doing the analysis for atlas,) to see how well we are transferring data within the UK.
So the overall figure is 93.22%. So with two retires allowed; on average 99.993 of transfers complete without having to worry about retrying from within the VO's Sounds good until you find out that last month ATLAS transferred nearly 6.5M files to and from UK sites, therefore ~45k files would have to be retried from the V0 framework. In total there were6417312 unique successful transfers (2.4M solely within the UK) and 467001 failures associated with them.
