NC031: Emergency server maintenance

26 April 2019 11:02:07 +0000

We will be upgrading server NC031 (the primary web server) with more memory to address memory shortage issues that have been affecting some websites recently. This maintenance is scheduled to start at 19:00 UTC on Saturday 27 April and is expected to take up to five hours, concluding before approximately 23:59 the same day. (Please use the World Time Server to convert this time to your time zone.) It is possible that the maintenance will take less time. During this time all websites (including the main NinerNet website) will be unavailable, for both browsing and editing.

This maintenance will not affect email.

We will post a notice here when the maintenance starts, progress updates on the hour every hour, and when the maintenance completes. We thank you for your patience as we work to improve our network’s reliability. If you have any questions or concerns, please contact NinerNet support.

NC031: Web server downtime

14 March 2019 21:34:49 +0000

The database on our primary web server (NC031) went down at 20:20 UTC, and was not brought back up until 21:00 UTC. This means that all database-driven websites were down during this 40-minute period, and would have displayed the message, “Error establishing a database connection”. We are still trying to determine why this happened and why the service was not automatically restarted, as should have been the case. Coincidentally — or perhaps not — at the same time the server was under a heavy load from hundred of thousands of requests on a single website, and we have now blocked the source of that traffic.

We sincerely apologise for this inconvenience. If you have any questions, please do contact support.

NC023: Secondary issue resolved

12 March 2019 20:26:33 +0000

The secondary issues referred to previously were not issues at all. A single test out of several failed, but the failure was unrelated to this server.

This issue is now closed. We apologise for any inconvenience this emergency maintenance may have caused while the server was offline between approximately 13:26 and 14:03 UTC.

If you have any questions, please contact support. Thank-you for your patience.

NC031: Emergency maintenance complete

26 December 2018 12:18:17 +0000

We took server NC031 (the primary web server) down for eleven minutes today to correct an issue related to memory usage. The server was offline between 10:32 and 10:43 UTC.

We will be replacing this server early next month, and migrating all websites to the new server.

Our apologies for this inconvenience. If you have any questions or concerns, please contact NinerNet support. Thank-you.

NC036: Maintenance complete

15 December 2018 19:57:20 +0000

Our scheduled maintenance to increase the storage space available for email accounts on the mail server (NC036) is complete. The ability to send and receive email was not available between 19:17 and 19:44 UTC. The expanded disk space has been tested and all is running normally.

If you have any issues or questions, please contact NinerNet support. Thank-you.

NC036: Scheduled mail server maintenance

14 December 2018 07:03:01 +0000

During this weekend’s maintenance window we will be adding hard drive storage to server NC036 to continue to provide more storage space for a growing number of growing email accounts. This maintenance is scheduled to start at 19:00 UTC and we anticipate it will last less than one hour.

During the maintenance the ability to send and receive email will not be available, both via standalone email programs (e.g., Outlook, Thunderbird, etc.) and the webmail. Incoming email will be queued on the sending servers until our server is back online again, after which it will then be delivered to our server and your email account. This may result in a delay longer than the planned hour of the maintenance though.

Please monitor this status page to be notified of the start and end of the maintenance. If you have any questions or concerns, please contact NinerNet support.

Thank-you for your patience as we continue to work to improve our services to you.

NC031: Database overload incident

14 December 2018 05:51:47 +0000

On 13 December (UTC) the database server on server NC031 (the primary web server) failed twice, the second time resulting in our deciding to reboot the server. We believe this to be the result of a marked increase in denial of service and hacking attempts against this server over the last few days.

The database server went down at 01:55. We immediately logged into the server to determine the cause, and restarted it at 02:37. Shortly after that the problem manifested itself again, we did a full reboot of the machine at 03:03, and the server was again online and fully functional at 03:06.

The database failure resulted in database-based websites — e.g., WordPress websites — generating “error connecting to database” errors.

This issue highlights an issue on this server that we intend to address very early in the New Year, that being a necessary upgrade of our firewall system to better handle such attacks in the future.

We apologise that this issue occurred. If you have any questions, please contact NinerNet support. Thank-you.

NC031: Data centre power failure

19 July 2018 05:09:49 +0000

At 23:04 UTC on 18 July connectivity issues were reported at the New York, US, data centre. The cause of this problem was later identified as a power outage. The data centre is currently reporting that power was restored to the data centre at 00:38 UTC on 19 July, but our own logs on the server itself indicate that it was only down between 22:55 and 23:50 UTC on 18 July. We are expecting a full report from the data centre and will post further details here when we receive that.

This affected our primary web server, hosting most clients’ websites, including our own primary website (www.niner.net).

We later soft-rebooted the server at 04:07 UTC on 19 July, and it was back online at 04:08.

This outage affected automated daily back-ups on the server. These have been restored and will run as scheduled at the next scheduled time, which is at midnight UTC on 20 July.

We apologise for this outage. The data centres we select are supposed to have redundant power systems to ensure that this kind of event never happens. However, clearly it did in this case and, as mentioned above, we are expecting a follow-up report from the data centre to explain this failure.

If you have any questions or concerns, please contact us to let us know. Thank-you, and we again apologise for this incident.
