Tue 18th September Report for the Experiments Liaison Report (17/09/2018) is here.
- Tier-1 have spent the last week in the process of trying to resolve the on-going LFC issues.

We don't often see metadata showing a file-size of 18446744073709394047 bytes (yes, we think that's a yottabyte or two), and feel this may be causing some undesired functionality!
- We have restored back to a version of the database that works with gfal-copy (i.e. doesn't throw the error people were encountering) and are now working out what's missing and corrupted between the latest working and rolled back version of the database.
- This issue was successfully resolve with the removal of the GOCDB unscheduled down-time at 12:00BST 24/9/18.
