Unfortunately the deployment did not go as planned and resulted in longer downtime than was expected. We had problems with the virtualisation infrastructure not seeing the new routers and therefore not being able to reach the outside world. After 25 minutes we decided to roll back the change and reconnect to our old routers which reconnected successfully.
We will be analysing the logs and outputs from the work to understand what went wrong and be able to redeploy the change successfully at a later date.
