36 Open UK Tickets today.
TIER 1
138665 (4/12/18)
My apologies for being a nag, but this MICE LFC ticket still hasn't had an update this side of Christmas. Could someone please take a look and update the ticket (or at least re-acknowledge the ticket's existence). In progress (12/12/18)
138500 (26/11/18)
This CMS transfer ticket is a little quiet, although I suspect that's due to a lot of conversation going on along other channels and work is ongoing on the issue. Are my suspicions correct? In progress (17/1)
QMUL
139097 (7/1)
In a similar nagging tone, no words have been added to this ticket, from either side (site or LHCB). Is the issue still an issue now that (I believe) the works at QM are finished? In progress (8/1)
ECDF
139240 (21/1)
A comment aimed at LHCB rather then the site - have you been able to check that the issue at hand (which looked to be a classic black hole node) has been dealt with? The last report from the VO mentioned there were other issues preventing seeing if things were solved. In progress (22/1)
BIRMINGHAM
137801 (17/10/18)
The aspirational switch off date for the Birmingham DPM was yesterday. How did that go Mark? Do you now feel like a huge weight is off your shoulders? In Progress (22/1)
LIVERPOOL
138943 (19/12/18)
Just in case the Liver lads haven't seen it, this LHCB transfer issue is no more and the ticket can be closed. In progress (28/1)
BRISTOL
131613 (3/11/17)
To keep with the positives, the Bristol IPv6 ticket looks to be almost finished with - firewall ports are open so we just need to see if PS tests run fine. Nice. In progress (29/1)

39 Open UK Tickets this week.
First a look at a few regular tickets:
TIER 1
138665 (4/12/18)
This MICE LFC ticket that was mentioned last week still could do with some attention, it still hasn't been updated since last year. It looks like a connection issue (and a bit of an odd one at that). In Progress (12/12/18)
RALPP
139222 (18/1)
A ROD ticket for webdav test failures. Chris has asked where to get some help with figuring out the error code seen when the test fails - the test description link in the ticket appears to be broken. In progress (21/1)
QMUL
139097 (7/1)
Any luck fixing these LHCB data transfer failures? In progress (8/1)
THE IPv6 TICKETS
OXFORD: 131615
Kashif provided a comprehensive update at the start of the month - it looks like some progress is soon going being made, although it looks like it will be a slow process due to the low priority of IPv6 with the Oxford networking people. On Hold (7/1)
BRISTOL: 131613
Things are looking positive at Bristol, just waiting on some holes in the site firewall for the perfsonar boxen. Any luck with that? In progress (21/12)
BIRMINGHAM: 131612
More positive news, the new central infrastructure is in place and so hopefully Mark can have a go at dual-stacking soon (I assume after he's killed off his DPM). On Hold (24/12/18)
GLASGOW: 131611
Sadly not so positive an update from Glasgow - Gareth explained how their perfsonar revealed v6 traffic issues when it was dual-stacked (which is its job), so they're waiting on this getting fixed. Luckily the usual sticking point of v6 reverse DNS isn't an issue. In progress (4/12)
ECDF: 131610
Rob explained in the last update how the physical migration of the site *didn't* break the v6 connectivity of the perfsonar and test DPM (yey!). Dualstacking the production storage was predicted to start around nowish (give or take a month I assume). Any recent news? Now worries if there's not though. In Progress (4/12/18)
DURHAM: 131609
Adam forwarded Duncan's information about the JISC Secondary DNS service to the Durham networking team - v6 packets can otherwise flow (just no DNS!). Any word back from them? On Hold (4/12)
SHEFFIELD: 131608
There was hope that the perfsonar box could be dualstacked in November, but I assume the usual end of the year rush happened. Any luck dual-stacking it this year? An update for this ticket would be great. In progress (30/10/18)
MANCHESTER: 131607
Manchester got a shiny new IPv6 range towards the end of last year. Any luck dual-stacking your storage yet? Any timeframe for doing so if you haven't got round to it yet? In progress (3/12/18)
LIVERPOOL: 131606
John gave a nice chunky update last month - the site stands ready to dualstack their storage, but just waiting on getting the WAN routing fixed (hopefully sometime soonish). But at least their perfsonar is happily v6'd. In Progress (5/12/18)
RHUL: 131603
At last check RHUL were waiting on v6 DNS before they could proceed. Simon reported that RHUL were looking at outsourcing this service to JANET, but no word on if/how well that's going/gone. Any news? An update would be appreciated. In progress (29/10)

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? Update - both tickets have been looked at further, the Liverpool ticket was a firewall issue and should be fixed. Chris has looked into the RALPP errors and is a little confused as there don't seem to be any v6 routing problems but there are too many v6 transfer failures.
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.
Extra Extra 139152 - This Sheffield LHCB ticket from the weekend seems to have been missed, it looks like there might be a black hole node gobbling up LHCB jobs.
