Option 2 preferred for efficiency, but Option 1 decided on Option 1 would be simpler to implement for a temporary fix, as the move would be reversed antares tpc nodes to be moved to an echo leafsw, to confirm ipv4 real estate with James | ||

Site reports
Lancaster: Our scrubbing stats suddenly picked up last Friday, we’re not sure why but we’re not complaining.
Manchester also noticed similar problems with mclock (3 objects/hour with mclock). changing settings didn’t seem to have an effect,
lots of scrubbing but not updating the scrub date (scrubbing a bit broken on reef)
Reporting bugs flagged upstream
Glasgow: targetting pacific for upgrade, waiting for Reef stability
RAL upgrade might go to Quincy
mid-upgrade (pacific mons + nautiluse osd) - osd maps are created very quickly, but can bloat mon stores
