Email maintenance: Update 2

30 September 2013 15:34:00 +0000

This maintenance continued through the weekend, but was not completed due to significant obstacles. At no time was the main mail server shut down.

We will attempt to finish addressing the obstacles today and aim to finish the maintenance early on Tuesday morning UTC. During that time the main mail server will need to be shut down, but we anticipate that this shut-down should not last as long as we had initially anticipated.

Email maintenance: Update 1

29 September 2013 01:15:51 +0000

This maintenance has started. However, we will not shut down the mail on the primary server until it is necessary to do so. We’ll post an update here when we do.

Email maintenance this weekend

27 September 2013 22:07:13 +0000

On Sunday, 29 September at 01:00 UTC, we will be performing some extensive maintenance of our email systems. This will necessitate shutting down the primary mail server for a period of time, probably for around two to three hours. Within 24 hours of the start of the maintenance, we will conduct a test that should give us a better idea of the amount of time needed.

During the shut-down the following services will be affected:

  • No new email will arrive in your email account, and
  • You will not be able to send email.

The following services will not be affected:

  • Websites will remain online,
  • You will still be able to log into your email account, and
  • If you host your email on a self-hosted server (i.e., you only have a web hosting associated with your account), your email will function as normal, as it’s not involved in this maintenance.

During the maintenance, any email sent to addresses on your domain will be queued on the senders’ mail servers. Once the maintenance is over, this email will be delivered to your account. No email will be lost.

This maintenance is necessary to improve your email service, and we thank you for your patience. Updates will be posted here leading up to, during and following the maintenance. Please inform colleagues, employees and anybody else using email on your domain.

If you have any questions, please contact support and we’ll be happy to assist. During the maintenance, email on the niner.net domain will also be affected, so we ask that if you need to contact us during that time, please either use the contact form on our website, or send email to:

support-september-2013@ninernet.com

To convert the time of this maintenance to your time zone, please use the World Time Server.

Thank-you.

Server NC018 web server restarted

24 August 2013 08:21:57 +0000

We have identified the particular websites that are being attacked and have made adjustments to try and deflect the attack. In the meantime we have restarted the web server and will continue to monitor the attack.

Additionally, the mail queue has now cleared.

NC018 web server stopped

24 August 2013 07:24:12 +0000

We have temporarily stopped the NC018 web server in an attempt to fight this attack.

Server NC018 under attack again

24 August 2013 07:08:51 +0000

As the title says, it appears that server NC018 is again the target of an attack. We are working to address the issue as quickly as possible.

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 issues

23 August 2013 15:54:34 +0000

Server NC018 appears to be suffering the effects of a denial of service attack. We are working to address the issue.

Server NC018 replacement: Update 14

9 June 2013 11:00:54 +0000

Our apologies for our silence on this issue. Work continues on this migration, but not at the pace at which it was happening a few weeks ago. We will, when we are finally in a position to finalise the migration, post an update here.

Thank-you for your patience and understanding.

Spam defences on server NC018

9 June 2013 10:58:16 +0000

Contrary to the last update on this topic, spam defences on server NC018 are indeed active most of the time. We monitor the server load and turn them off if the load gets too high. However, most of the time the spam defences are up 24 hours a day, 7 days a week.
