Monday 22nd October 2018, 14.30 BST
37 Open UK Tickets this week.

137801 (17/10)
For information only, the ticket charting the decommissioning of Birmingham's DPM SE. In Progress (17/10)

136635 (9/8)
Lancaster is having no luck shifting this availability alarm due to SRM CertLifetime checks erroring constantly, causing 100% "Unknown" status. Has anyone seen this before? Could we blag that it's a problem with the check? On hold (8/10)

137195 (14/9)
Any luck fixing the Castor LDIFs to clear these ROD alarms? (I don't seem to have permission to check the links to the tests myself). In progress (10/10)

136199 (18/7)
LHCB FTS ticket. Last update was a prod from Christophe last week asking if there's any news. In progress (17/10)

IPv6 Tickets
(with reference to the IPv6 site status table)

RALPP: 131616
No update for a long while on either the ticket or the table after some promising progress. In Progress (31/1)

OXFORD: 131615
Last update on the ticket back in July describes v6 as the blocker, is this still the case? On Hold (13/7)

Some nice progress with the site perfsonar boxen dual-stacked. The table is also up to date. Nice. In progress (8/10)

BRISTOL: 131613
Some recent discussion with CMS and Duncan, xroot works for v6 but srm/gridftp doesn't. I think steps have been made to fix this (from an entry in the table) but I'm not sure what they were! In progress (11/10)

Mark's update back in August painted a familiar picture of central IT dragging their heels. As ALICE consider v6 a necessary thing Mark has been asked to keep up the pressure. No recent update on the table. On hold (27/8)

GLASGOW: 131611
Some good progress here, with some v6-ining (or dual-stacking) of the perfsonar boxes and a hope to be able to dual-stack the storage by the end of the year. Duncan spotted a few problems (that might be ip6table related), but I understand Gareth was off last week. The table entry is up to date too, sterling stuff. In progress (12/10)

Dual-stacking has caused a lot of interesting times at ECDF. Rob gave a good update on their situation last month, and the table is up to date. Interesting that v6 traffic won't go through the JANET link for the site (it must have at one point, right?). Any recent news about dual-stacking your disk nodes? In Progress (10/9)

DURHAM: 131609
Adam provided an update last week, with (again) reverse IPv6 DNS being a sticking point (despite v6 traffic otherwise flowing fine). Adam's expected timeframe for being able to do a full v6 rollout is mid-2019. Whilst it's depressing it's good to know this ahead of time. No update on the table since 2015 though, but looking at the last entry there you could just change the date. In progress (should be on hold?) (17/10)

Things looked a bit hopeful with work in this area (re-)scheduled to start in July, but it looks like thing stalled. Any news? The table mirrors the last update. On hold (10/7)

The perfsonars are dual-stacked but IIUI v6 reverse DNS is again the sticking point that prevents dual-stacking the storage. The table entry is more up to date then the ticket. On hold (25/4)

The Liver-admins were waiting on new routers needed to sort out the site's v6 problems back in June. Any news at all since? Bad news is better then no news in this case. In progress (On hold it?) (4/6)

UCL: 131604
An update today that Ben is hoping to reinstall and dual-stack their perfsonar this week. As they have no storage that will be them sorted if it all goes to plan. In progress (22/10)

RHUL: 131603
Perfsonars are dual-stacked, but the v6 reverse lookup is a problem again which is a problem for storage. Table and ticket are up to date, but has this work been properly handed over to Antonio and Simon? In progress (10/9)
