Switchupgrades location BIT-1
Timeframe: 17-03-2026 0.00 - 6.00h
Impact: Medium-High
Impacted services: Network, Hypervisors at location
Dear customer,
On Friday, February 20th, we have sent out a general announcement about updates that we need to perform on networking devices in order to fix a number of bugs in those devices.
In the abovementioned timeframe, we will execute this maintenance on the location BIT-1. During the upgrade, the switches on that location will do a full reboot. During this reboot, servers connected to these switches will be completely unreachable. It will remain powered on, but there will be no network-connectivity. This will be the case at least twice during this maintenance.
Customers with hypervisors on this location are recommended to migrate any virtual machines they may have running on this location. Depending on the OS and configuration of the VM, this maintenance may cause loss of disk access in the VM. Tuxis will make sure that HA is completely disabled during the maintenance, to prevent unexpected reboots (Fencing), but we will not migrate the VM's for customers.
Tuxis services will be migrated to other locations, so this maintenance should not impact any services. However, due to the nature of this upgrade, we do send out a general announcement that our service may be impacted, and that the connectivity on other location may be impacted as well.
Update 0329: around 0145 one of the leaf-switches at BIT-1 did not come online properly after we upgraded the firmware. The system was unable to load its 10G interfaces resulting in systems not coming back online.
After this we decided to downgrade the firmware to check if that would resolve the issue. While downgrading the firmware we opened a support case with the vendor and started troubleshooting.
