- RIPE ATLAS probe experience pages.
- Automating ATLAS consistency checking (See Alastair's email 12/08)

- Reminder: The new Operations Portal is now online: http://wlcg-ops.web.cern.ch/. There is a request for volunteers to write articles on interesting topics for WLCG Operations. There is a section in the portal for this: http://wlcg-ops.web.cern.ch/articles, please, help us keeping the portal attractive and useful for everyone in WLCG by submitting an article where you share your expertise as a sys admin, member of an experiment, task force or working group coordinator, describing new technologies, experience running a service, etc. (LCG-ROLLOUT 6/08/15).
- GHOST - File registration error on SE with Dirac (Frederic).
Tuesday 4th August

- Security update: SVG procedure update. Because software used changing.Close working with CSIRT. No longer set 3 day Target Date (TD). Some vulnerabilities are policy violation issues - risk assess only. VM endorser should follow checklist. VM operator responsible for patching in VM. Both roles should receive updates. 29 RAT (Risk Advisory Team) members.
- ARGO updates: test environment; removed components (e.g. MyEGI) from SAM; production instance from September. Central results will use from October.
- UMD-4 & MW updates: UMD 3.13.0 released 1st July. Minor releases during July to fix bugs. Goal to have latest products ready for release within 2 months. UMD-4 - several packages EPEL7 ready. Integrating FedCloud products ongoing.Looking for early adopters for: ARC clients; DPM-mysql; gfal2; squid; CVMFS; CentOS7....

Tuesday 25th August
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- The Tier1 routers have been working OK since the intervention over two weeks ago. There was a transparent intervention on the 18th August when the borrowed primary router was taken out of use and our own router put back in its place.
- Plans for upgrading Castor disk servers OS during second are firming up (provisionally for 26/27 August). Also finalizing plans for updating the Castor Oracle database during September/October. (See dates in report linked just above).

Wednesday 08 July
- Huge backlog of ATLAS data from Glasgow waiting to go to RAL, and oddly varying performance numbers - investigating
- How physics data is like your Windows 95 games
Wednesday 01 July

- Data transfers, theory and practice
- Somewhat clunky tools to set up but perform well when they run
- Will continue to work on recommendations/overview document
- Worth having recommendations/experiences for different audiences - (potential) users, decision makers, techies

- [John Gordon] "Of the WLCG sites we now have 97%+ of cpu reported with cores. I expect you all saw my recent email to GDB naming 16 sites. If one German and one Spanish site and the four Russians start publishing we will jump to 99%+"
- New list of sites needing to update multicore accounting being prepared this evening (Monday) by Vincenzo
- SL5 decommissioning date March 2016;
- Next meeting 10th August
Monday 15th June
- There was an EGI operations meeting today: agenda.
- New Action: for the NGIs: please start tracking which sites are still using SL5 services: how many services, and for each service if still needed on SL5, if upgrades on SL5 services are expected). A wiki has been provided to record updates. Also interesting to understand who is using Debian.

Tuesday 12th May
- MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy.
Tuesday 17th March
- Daniela has updated the [ https://www.gridpp.ac.uk/wiki/Staged_rollout_emi3 EMI-3 testing table]. Please check it is correct for your site. We want a clear view of where we are contributing.
- There is a middleware readiness meeting this Wednesday. Would be good if a few site representatives joined.
- Machine job features solution testing. Fed back that we will only commence tests if more documentation made available. This stops the HTC solution until after CHEP. Is there interest in testing other batch systems? Raul mentioned SLURM. There is also SGE and Torque.

Monday 24th August 2015, 15.45 BST
21 Open UK tickets this week, most being looked at or are understood. There will be no ticket update from Matt next week (1st September) either, as he will be flapping about during a local downtime.
YE OLDE GGUS TICKET LINK
114460 (gridpp pilots at Sheffield) could do with an update. The Liverpool ticket discussed last week (114248) has received an update from the user saying that the ticket can be closed. As Steve mentioned last week the underlying issue is still very much there, but I don't think this ticket is a suitable banner for us to fight that battle under.
T'Other VO Nagios Page
As usual nothing to see here at time of writing, sites are doing a grand job of working for the monitored VOs.
And that's all folks! See you in Liverpool.

Tuesday 09 June 2015
- ARC CEs were failing nagios test becuase of non-availability of egi repository. Nagios test compare CA version from EGI repo. It started on 5th June and one of the IP addresses behind webserver was not responding. Problem went away in approximately 3 hours. The same problem started again on 6th June. Finally it was fixed on 8th June. No reason was given in any of the ticket opened regarding this outage.
Tuesday 17th February
- Another period where message brokers were temporarily unavailable seen yesterday. Any news on the last follow-up?
Tuesday 27th January
