I went down the rabbit hole and started a table of core (not consortia or project specific) services/infrastructure maintained in the community. It would be useful to know what these are and who are admins for each - so we know who to contact. I have left some blanks to fill in, perhaps the infrastructure and deployment themes can discuss what should appear here, there is probably a lot more.
If you are a voting member of the community you will already have wiki access to edit and upload details into the table. For those without wiki access please comment below and we will check one of the admin can add you.
