Hello everyone,
as part of making the infra work more open and more transparent, and as an explanation why things sometimes take much longer than planned, find here my very personal todo list for infra tasks:
https://wiki.documentfoundation.org/Infra/Todo
Some security-sensitive items have been removed, and the migration to the infra 2.0 platform and new servers is not listed as separate item.
Note that the list is totally unsorted and unprioritized at the moment, but I plan to eventually add it to some tracker or task managemenet software, allowing others to add (and work on 
items.
Enjoy,
Florian
