A quiet Christmas period. 

In December there was an issue with AAA when under load. OOM errors were observed...to be followed up. 

The number of failures on the ARC-CEs really increased over the holiday and since then. The SAM status never goes red though, because all 5 CEs have to fail simultaneously. So we are lucky so far. Tom Birkett is investigating. 

Number of jobs being run by CMS is suspiciously variable, despite there being avaialble work in the system. Could this be related to the above CE failures?

Job performance is as good or better than other CMS T1s. 

Tier 2 mini-DC testing was done in week of 9th December. Tier 1 tests to be planned.
