We suffered an outage on our mail server mail.anu.net this morning which lasted from 05:50 to 08:27 CET. During this time no mail was delivered and users may have experienced difficulty logging in. The fault has now been rectified and all pending emails have been delivered to users mailboxes. Apologies to all our Hosted Email customers for the inconvenience caused.
[Resolved] Node failure usa1-xen-1
We encountered errors on the console of the Xen node usa1-xen-1 (Chicago datacenter) this morning. The on-site technician has determined a hardware fault is the root cause. We have migrated all affected VMs to other Xen hosts and service has been fully restored.
Hosted Email storage upgrade
Update 2013-12-12 22:28 GMT
The migration is complete and all Hosted Email services are now back up and running on the new SSD RAID array.
There was one minor issue that arose during the migration: the time on the new server was running fast by just over 2 hours, and the clock did not sync immediately at startup time, so a few emails were delivered with timestamps in the future. Sorry about that.

We’ll be adding additional storage space to our mail.anu.net Hosted Email server tonight at approx. 22:00 GMT
We are also taking the opportunity to migrate all the mail storage from 7200RPM SATA disks to new SSD drives, bringing big performance increases and lower energy usage.
A short interruption to service is unavoidable but we’ll do our best to keep the downtime to a minimum. We’ll update this post to confirm when we’re done. Apologies in advance for any inconvenience caused.
