Xen security updates

8 March 2015 12:27:53 +0000

Some of our servers use a technology called Xen. Like all software, it is subject to the discovery of bugs and security vulnerabilities.

Over the last week, all of our servers that use Xen have undergone “patching” to address some newly-discovered — but not yet publicised — security vulnerabilities. This patching required servers to be rebooted, and finished this morning.

We thank you for your patience this week during these upgrades.

NC027: Update from data centre

9 December 2014 10:40:41 +0000

Further information from the data centre on the reboot of server NC027 indicates that there was a hardware management issue in the data centre that necessitated a reboot of this server to maintain and improve stability of this machine. The issue was addressed with a software upgrade during the downtime, and we have been assured that this addresses the issue and will not happen again.

If you have any questions about this, please contact NinerNet support. Thanks again for your patience and understanding.

NC027: Hardware issue update

8 December 2014 20:03:00 +0000

We have determined, through log analysis, that server NC027 was shut down at 14:03 and restarted at 14:24 UTC. So the server was unavailable for 21 minutes this afternoon.

Any email sent to addresses on this server would have been queued on the sending servers until this server was back online, and would have been delivered at that time or shortly thereafter. You will have received any such email by this time.

When we receive more details from the data centre we will post them here. We apologise for any inconvenience caused and will post additional details here as soon as we have them. Thanks for your patience.

NC027: Upgrade complete

22 November 2014 20:15:20 +0000

The maintenance on server NC027 to increase the RAM, increase bandwidth capacity and move to solid-state drives has been completed. It took far less time than we expected, which is a good thing of course. The server was taken offline at 19:20 and was back online at 19:41 UTC.

Systems have been checked and everything appears to be operating normally. If you have any questions about this upgrade, please contact NinerNet support to let us know and we will be happy to answer your questions. Thanks very much for your patience and understanding.
