NC018: Issue resolved

5 May 2014 08:15:06 +0000

Web server performance on server NC018 has returned to normal. Thank-you for your patience.

NC018: Web server slow

5 May 2014 07:45:40 +0000

Some websites on server NC018 are loading quite slowly. This does not seem to be affecting other services such as email.

We are looking into the cause and will report back here.

NC027: Investigation findings

26 January 2014 16:00:09 +0000

Server NC027 (the new mail-only server) experienced a great and very brief increase in activity at about 04:00 UTC on 23 January, and we suspect that this lead to the server getting behind in scanning and processing email. The hard drives simply couldn’t keep up.

In order to allow the server to catch up, we disabled virus and spam scanning. Over the course of the coming week we’ll be re-enabling each of these (inbound and outbound) one at a time per day. This will allow us to determine which activity is the bottleneck and make finer adjustments accordingly. We also have a back-up plan to move the accounts on this server to one with faster (solid-state) drives, if necessary.

We apologise again for the inconvenience of significantly delayed email on Thursday. If you have any questions about this incident, please contact NinerNet support. Thank-you.

NC027: Mail queue almost clear

23 January 2014 14:48:04 +0000

The mail queue will be cleared within the next 20-30 minutes.

Once the queue is clear we’ll be looking for a cause for this incident. There was a great spike in activity on this server around 04:00 UTC, and it’s quite possible that the initial back-up started around that time and didn’t quite manage to catch up.

NC027: New mail delivered immediately

23 January 2014 13:25:21 +0000

Since reconfiguring the mail server we’ve noticed that new email is being delivered right away. It is now only the backlog that is still slowly being processed.

NC027: Performance improvement

23 January 2014 11:55:41 +0000

We have made some adjustments to the configuration of the mail server on NC027 and as a result the mail queue seems to be clearing, albeit very slowly. We’re continuing to work on this to speed up delivery.

Server NC027 performance degraded

23 January 2014 09:07:10 +0000

Server NC027 has a large and growing mail queue, but the server is up. We are investigating and will post updates here.

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.
