Arzhel discovered that the labstore1006,7 boxes are using their internal 1G nics. They should have 10G ones, as they were ordered with them (see T161345). They are racked in 1G racks, which means they will need to be moved. This should be scheduled, and then the 10G nics set up in the bios for use.
After discussing with Chris, the current proposal is to move labstore1006 from A1 to A4, and cross-patching to A5 (10G enabled rack), and labstore1007 from D6 to D2 or D7, that are both 10G enabled.
