Summary:

Due to a bug in the firmware of leaf switches in BIT-2D, it is necessary to upgrade this firmware. During this maintenance all aforementioned switches will be upgraded and rebooted. Customers with a redundant connection will see their network links go down and up in turn. Customers with a single network connection will be disconnected for a few minutes.

Details:

The leaf switches appear to have a bug where a process is slowly claiming more and more memory. Ultimately this will result in lack of memory and eventually downtime. A firmware upgrade is required to prevent this. This upgrade will result in network disruption of a few minutes per switch. To minimize impact for customers with a redundant network connection, the switches will be upgraded and restarted one by one. Customers with a single network connection in BIT-2D will not be connected for a few minutes during the switch reboot. On your invoice you can find whether you have a connection to one of the aforementioned switches.
