Scheduled network outage

Impact: A 1 hour network outage
Services: All web and email services
Date: Wednesday 30 April 2008
Duration: 00:05 – 01:05 AEDT
Status: Resolved

We require a one hour outage window to build redundancy into our cluster load balancers. This is one of the remedial steps outlined in our report into the unscheduled outage on 31 March.

Update: 12:05 AEST – commencement of the scheduled outage is occurring as planned.

Update: 12:17 AEST – the upgrade is proceeding as planned, whilst there may be some short connectivity losses, there should not be any extended outages at this stage

Update: 01:15 AEST – normal service has been restored and the planned upgrade has been completed. Some final tests are underway which may cause a further two minute outage for some services. During the bulk of this work tonight most services would have only experience brief outages. The exception to this is the Power cluster, which experienced 15 minutes of intermittent connectivity. The cause of that has been successfully identified and has now been fixed.

Update: 01:39 AEST – final testing has been completed and all services are now operational.

One of the servers in our SMTP mail cluster has built up a large queue. Technicians are currently working on clearing the queue at the moment however there will be a delay on mail waiting on that server’s queue. Any new mail will be processed immediately.

Update 09:55 AEDT: The size of the mail queue on the affected server is coming down now. It has been taken out of our cluster so that it does not accept any new mail. The mail queue is expected to be back to normal within the next 30 minutes.

Update 10:42 AEDT: The email queue is back to normal now.
