ATLAS monitoring shows first week (since Dec, when MONIT goes back to) that RAL reports meeting the pledge value (avg: 129k vs 132k pledge HS06 slots)
(Am hoping to conclude study into consistency between atlas monitoring / WLCG shortly).

Data Carousel:  Data16 staging submitted 11th March;  No problems observed or reported

High failure rate in AODMerge jobs (initiated from the data-carousel RPVLL reprocessing),
batch system kills due to wallclock. Related to the stage-in / stage-out slow transfers.

UK sites next in line for migration to Grand-Unified Queues (Merging of analysis and production).
Was expected this week; no update solar.

Requested a Rucio consistency check on files in Echo; last check done from November snapshot.
