Despite running unattended over the Christmas holidays, ScotGrid sites were by-and-large available.
From 2006-12-20 to 2007-01-03 SAM status for each site was:
ScotGRID-Edinburgh: SAM test pass rate 241/338 = 71.3%
(Failures: JS 3, RM 94)
scotgrid-gla: SAM test pass rate 324/338 = 95.8%
(Failures: JS 4, RM 10)
UKI-SCOTGRID-DURHAM: SAM test pass rate 318/338 = 94.1%
(Failures: JS 6, RM 14)
UKI-SCOTGRID-GLA: SAM test pass rate 328/338 = 97.0%
(Failures: JS 1; RM 9)
Looking at the JS and RM failures for everyone except Edinburgh these seem to be at the level of grid flakiness caused by higher level services failing or timing out (e.g., RM test times out, BDII fails to respond, etc.). So our only significant problem was issues with Edinburgh's dCache, which did seem to be unreliable.
Any comments Greig? Did you have to intervene?
