| + | We got ticketed about our tickets! Or to be more exact, we had too many "very urgent" tickets last month that weren't responded to within 1 working day. Of the three such tickets, the QMUL one was well understood, whilst I suspect the Oxford and RALPP tickets were simply missed (and I'm not sure how very urgent they were). So please please set your tickets in progress as soon as you start them, otherwise I have to deal with tickets about tickets, and that's a bit too meta for me! In progress (7/8) |

- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).
Tuesday 4th July
- Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).
Tuesday 6th June
- An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.
Tuesday 25th April
- perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here
- Duncan has recreated the UK perfSONAR mesh. Link here!
