The Dirac instance at Imperial isn't production quality yet, but I think
that is the way we should be moving.

Updating:
https://www.gridpp.ac.uk/wiki/Wider_VO_issues
Would be helpful - with links to storage group advice on this.

I have to send my apologies (at the GDB).
QMUL turned on IPv6 on one of our two GridFTP nodes at 13:00 on Monday.
Simon Fayer ran a load test - which transferred 15098 files of
1073741824 bytes (1GB) in size. That's 15TB.
Here's the traffic graph.
There are issues with configuring the FTS so that transfers go over IPv6
when then can, but avoiding things failing if they can't.
