Server NC018 denial of service attack

23 August 2013 20:55:10 +0000

Server NC018 suffered a denial of service attack beginning at approximately 07:40 on 23 August, UTC. This continued until the server succumbed under the load at about 12:40. This affected all functions of the server: websites, sending and receiving emails, databases, etc.

Unfortunately we did not respond to this situation in a timely manner. This was partially because automated monitoring of server functions had been turned off due to an increasing number of false alarms from the system.

Once the server was rebooted at 13:47 and the attack mitigated, the server then still had a backlog of several thousand emails to process. This took several hours, with the queue being cleared by about 18:35. While emails were “missing” for several hours, no emails should have been lost; they were just delivered several hours late.

We sincerely apologise for the disruption caused by this event. We will reinstate monitoring and the associated actions that are taken when monitoring alarms go off.

We will shortly be responding to all emails and phone messages regarding this incident. If you have any further questions about this event, please contact us.

Server NC018 maintenance this weekend

6 March 2013 11:28:51 +0000

To address recent performance issues, we will be doubling the RAM on server NC018 during our regular weekly maintenance window this weekend. This will require that we shut down the server, open it up, install the new memory, and then turn the server back on again. During the few minutes this will take, the server will be inaccessible for all functions.

Here are the details:

Maintenance window: Saturday 9 March 2013, 16:00-17:30 UTC/GMT (90 minutes)

Please use the World Time Server website to convert this time into your own time zone.

Please note that although the maintenance window is 90 minutes long, the server will only be down for a few minutes sometime during the window, most likely right at the beginning.

Server NC018 is our primary server, and hosts your email and most websites. While the server will be down for a few minutes, no email will be lost, although it will be delayed a few minutes.

This status website will remain online during the maintenance, and will be accessible at status.ninernet.net if you are unable to reach it at status.niner.net.

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