0) Update on DSIT underspend bid [DB]
No news on the DSIT underspend other than the extended case was submitted and SV got back to DB on Friday and said thanks and they would let us know if they hear anything.
1) Feedback EGI CSIRT F2F in Glasgow [SS]
-Thanks for organising this event SS.
-there were 12 physical attendees (one last minute)
-Feedback from Matt and David Cr was that it was very useful and it went well.
-in terms of GridPP Security, DB and SS met DK, DCr + Matt prior to the meeting to discuss some matters.
– The Security checklist was discussed; this is at a draft which needs a core Tier-2 to beta test it (probably Glasgow). Schedule for this in general is for all sites to be set it in Q1 2026 for report at GridPP55.
2) NCR Phase 2 Expression of interest
JH, Pete and AD met to discuss disparate applications for the NCR expression of interest and their coordination.
Key points:
-Jon is intending to submit an expression of interest on behalf of IRIS.
AD said they could use RAL or other GridPP sties as “hosts” or potential locations on this bid, if they
-AD and Pete will also submit. Expand the data management side of things on this application.
3) Future Computing Initiatives
George Madden got in touch with PC and DB last week about a potential opportunity. (Details have not be shared at present)
ACTION –
DB will send DCos an email for a heads up and to see if he would be interested, with the limited information they can share.
PC will maybe follow up with George, to see if he will allow further detail sharing.

SI-4 Operations Meeting Report [SS,PG,PC] –
Discussion of Lancaster’s transfer ticket which revealed that some regions are still using SHA-1 signed certificates (and CAs). This is a potential security issue – SHA-1 has been considered retired for some years now, and modern distributions disable support for SHA-1 signed certificates by default. WLCG discussing a deadline for regions migrating from SHA-1 [RJ notes also to be discussed in MB tomorrow]
Report given from Rucio Workshop that KE and AF attended. Astronomy is a growing second influence on Rucio development, with its own distinct needs and philosophy from HEP.
