Other "needs discussion" topics

Corrupted shard object - #Ops-725

- Julien is very in favour of having a developer learning the object store implementation in details, so that problems like this can be resolved quickly. This needs to be discussed in more detail when Michael is back.

Meeting Rooms

• Room 513/R-068 is booked every week, until the EOY, for the CTA dev meeting.
