We identified a cabling issue on 2 different switches in DC5 on rack B6.
It will be required to disconnect and reboot both switches, causing a short network outage on the lower half of B6.
However, there is no electrical outage planned, only network will be unavailable.
Status will be updated as soon as it's started, at 0800Z (1000LT).
Switches have been rebooted and they are now working as expected.
Thank you for your patience.
