13:46 → 13:47 VO Liaison CMS

Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))

No progress on the IPv4 network slowness. It seems DI are occupied with an outage. 

Efficiency has been mostly very low. Failures are a bit higher than I'd like, but could be accounted for by LogCollect failures.

There's a ggus ticket concerning transfers from RAL. Possible issue with gridmap file? Marcello is looking into it.
