Update on server NC018

19 March 2013 12:58:28 +0000

As we informed you on 6 March, we had intended to increase the memory (RAM) on server NC018 on 9 March. (Server NC018 hosts the majority of websites, and all email except specialised email services.) This maintenance would have solved performance issues that were happening with more regularity. However, the maintenance failed due to hardware compatibility issues.

When the maintenance failed, we immediately began preparing to acquire new hardware to replace this server. During the week of 11-15 March we obtained a number of proposals and advice on a plan we had begun developing some months ago.

However, on 18 March the mail server was overwhelmed. The most obvious result of this was that email delivery was delayed during peak periods by as many as several hours. While it was not clear exactly why the mail server was overwhelmed, there was an obvious way to deal with the problem. We implemented this, and the mail queue was cleared in a short amount of time. We believed that this approach should have worked to prevent the mail server from being overwhelmed if the mail server again experienced heavy volume, but it did not when the same thing happened on 19 March.

We are therefore urgently preparing to set up new hardware. I don’t have an exact time line for you at the moment, but it is our goal to have the hardware in place and online by the weekend, and we will endeavour to transfer everything as quickly as we can over the weekend.

We will update you on major events by email, but please check our status page once or twice a day at status.niner.net or status.ninernet.net for progress reports.

We apologise for the inconvenience that this transition is causing, and ask for your patience as we go through this upgrade.

Mail processing on server NC018 back to normal

18 March 2013 20:58:04 +0000

The mail queue on server NC018 has been cleared, and anti-spam services have been reinstated. We apologise for the inconvenience, and are working on this server to bring these problems to an end.

Mail queue on server NC018 diminishing

18 March 2013 19:11:36 +0000

We have temporarily disabled some of the ant-spam services on the server to allow the mail queue to be processed as quickly as possible.

Mail queue on server NC018

18 March 2013 16:23:27 +0000

The mail queue on server NC018 — the mail server for all clients who host their email with us — is very large at the moment, and message delivery is being delayed. We’re working on this, and will post updates here.

Server NC018 back to normal

22 January 2013 22:02:06 +0000

The entire email backlog was processed by about 17:00 UTC, and the server is back to normal.

Again, we apologise for the inconvenience. Please contact support if you have any questions or concerns about this incident. Thank-you again for your patience.

Server NC018 update

22 January 2013 13:46:15 +0000

The primary mail server is working its way through the mail queue, and the queue is being reduced at this time. This is an improvement over what was happening earlier.

We will keep posting updates until this situation is resolved. Thank-you for your patience, and we apologise for the inconvenience.

Server NC018 update

22 January 2013 12:28:14 +0000

We are working with the data centre to block a distributed denial of service attack (DDoS) and clear the mail queue.

Mail queue on server NC018 backed up

22 January 2013 11:33:23 +0000

The mail queue on server NC018 (the primary mail server) is currently significantly backed up. We’re looking into the cause of the problem and will post updates here.

Server NC020 maintenance complete

29 September 2012 22:50:09 +0000

Maintenance to upgrade server NC020 was successfully completed at 20:51 UTC. The server was down for a total of four minutes during two reboots between 20:27 and 20:30, and 20:50 and 20:51.

If you have any questions or concerns, please contact NinerNet support. Thanks.

Server NC020 maintenance

28 September 2012 17:36:34 +0000

We will be performing maintenance on server NC020 during our normal weekend maintenance window this weekend to increase its capacity. This window opens at 19:00 UTC on Saturday, 29 September. (Please see theĀ World Time Server to convert this to your time zone.)

We expect fewer than five minutes of downtime during this window, and this should occur between 19:00 and 20:00 UTC. However, we expect it is most likely happen within a few minutes after 19:00.

Server NC020 is more commonly known as the PHP 5 server, and for the most part runs websites (WordPress, Joomla, etc.) that require PHP 5. It also processes mail for parked and aliased domains. No email will be lost during the maintenance, but it may be delayed for a few minutes.

If you have any questions or concerns about this maintenance, pleaseĀ contact NinerNet support. Thank-you.
