Cumulus switch upgrades

Scheduled Maintenance Report for REANNZ Advanced Computing and Data Services

Completed

We've identified the reason behind the lack of failover and restored services. A further preparatory change is needed before we can complete the original upgrade, so this will be rescheduled.

Update

We've encountered an unexpected lack of failover behaviour in our software-defined networking stack during the first stage of this upgrade while attempting an "orderly" failover and shutdown. There is currently intermittent connectivity to/from services and the Internet while we debug further and assess whether the change can continue.
