40 Open UK Tickets this week.

T2K DFC Migration on DPMs
Liverpool: 138648
Oxford: 138647
Sheffield: 138649
Lancaster: 138365

A quick summing up of these tickets- to provide the information T2K need (namely adler32 checksums for files that don't already have them) it appears your DPM needs to be DOME'd. At Lancaster seem to be having the most luck with this so far so please feel free to prod me about it.

v6-looking transfer problems
Liverpool (lhcb): 138943 (19/12)
RALPP: (atlas): 139127 (10/11)

Whilst for different VOs there's a common theme to both of these tickets - it looks like the failing transfers are trying to use IPv6. Any thoughts?

Bristol LHCB Ticket
138402 (21/11/18)
Are the issues described in this ticket still happening? That might be a question for the VO rather then the site. (6/12/18)

Last Year's Tier 1 Tickets:
138665 (LFC access issues)
138500 (CMS transfer failures)
138361 (T2K DFC migration)
A quick note that none of these tickets have had an update from the site yet this year to indicate that they've been picked up again after the Holiday break.

Monday 20th November

• The WLCG dashboard is available here: http://dashboard.cern.ch/.
• Please review the results on Steve's test pages.

Tuesday 18th July

Monday 20th November

• Tom Whyntie has requested (and been granted) access to the GridPP VO to get some pipelines working for large-scale processing and analysis of MRI scans associated with the UK Biobank project.
• All VOs in the incubation page being prompted for updates by the end of November (required input for OC documents).
• QMUL (Steve L) is following up on the biomed MoU. GridPP want to be cited in research papers for the support our resources/sites provide.
