23:07: This maintenance has been completed without issue.
We will be replacing our sip proxy with a more robust load balancer. The new unit has been configured and simply needs to have its IP changed to match that of the old unit. Unfortunately due to firewall configurations on customer premises it is not possible to complete a soft DNS change.
This work will commence: 23:00 – 20/11/2008
The planned period of downtime is < 5 minutes. If the upgrade should fail, we will revert back to our previous configuration.
