NC023, NC027 and NC031: Spectre maintenance

25 April 2018 11:41:21 +0000

Per our previous blog post, three of our servers will be updated to address variants 1 and 2 of the Spectre vulnerability per the following schedule (start times) in chronological order:

As with the previous upgrades for the Meltdown vulnerability, the maintenance windows for each are two hours long, but we expect that each server will be down for much less than that. During the Meltdown maintenance the servers were down for between 13 and 19 minutes, and we expect much the same this time around.

Please click the links above to determine when this will be in your time zone.

During the maintenance of servers NC023 and NC027 you will not be able to send or receive email. Incoming email to your domain will be held on the sending servers until our mail server is back online, and will then be delivered to your accounts. No email will be lost. Please note that email to NinerNet will also be down during the maintenance on server NC027.

During the maintenance of server NC031 your website will be inaccessible, both to you and the public.

NC023 and NC027: Maintenance complete

19 January 2018 03:30:26 +0000

Server NC023 was down for maintenance between 03:00 and 03:18 and server NC027 was down for maintenance between 03:02 and 03:15, and both have been successfully updated with current patches. This phase of the maintenance protects against Meltdown; further maintenance for protection against Spectre will take place when patches for it have been developed.

Updates will be posted here.

NC023 and NC027: Emergency server maintenance

18 January 2018 02:54:25 +0000

Per our previous blog post, the next of our servers to undergo updating are NC023 (the relay server) and NC027 (the primary mail server). The maintenance windows for each are two hours’ long, but we expect that each server will be down for much less than that.

The maintenance window for both starts at:

Please click the link above to determine when this will be in your time zone.

During the maintenance you will not be able to send or receive email. Incoming email to your domain will be held on the sending servers until our mail server is back online, and will then be delivered to your accounts. No email will be lost.

Please note that email to NinerNet will also be down during the maintenance on server NC027.

Meltdown and Spectre hardware vulnerabilities

17 January 2018 13:58:43 +0000

As you may have heard and read in the news since the beginning of January, major vulnerabilities in very widely used computer hardware (not software) were discovered in mid-2017 by security researchers in Austria, Germany, the United States and Australia, and were publicised on 3 January. Fixes to mitigate some of the vulnerabilities are now being released, and further mitigating measures are under active development where such mitigation is possible.

To this end we will be applying patches to our servers starting tomorrow (18 January) that will necessitate some down time. Due to the nature and scale of this problem — illustrated by the answer to the question, “Am I affected by the vulnerability?” being a simple, “Most certainly, yes” — these patches cannot be delayed or scheduled for a more convenient time. Also, as work continues on ways to mitigate some of the vulnerabilities, there are some updates to the operating systems on our servers that are yet to be developed that will need to be applied in the future. As further related maintenance takes place we will link back to this post.

Following this blog post we will post the details of the first server to undergo patching.

Further details on these vulnerabilities can be read at the following links:

If you have any questions or concerns, please feel free to contact us. Thank-you for your patience.

NC023: Server migration complete

19 November 2017 01:32:47 +0000

The migration of the relay server to new hardware has been completed. The server was offline between 20:20 and 20:39 UTC. Additionally, it now has more disk space and is accessible over IPv6 as well.

NC023: Sever migration starting now

18 November 2017 20:21:05 +0000

The relay server migration will be starting within the next few minutes.

NC023: Migration of relay server to new hardware

17 November 2017 07:22:19 +0000

Server NC023 (the relay server) will be migrated to new hardware during our regular weekly maintenance window this weekend. This maintenance will start at 20:00 UTC on Saturday 18 November 2017, and should conclude within an hour. During this time the relay server will be offline.

This maintenance only affects clients using the relay mail server; it does not affect operation of the regular email server that processes the vast majority of the mail carried by NinerNet.

We will post an update here shortly before, at the start of and following the maintenance.

If you have any questions or concerns, please contact support to let us know. Thank-you.

All servers: SSL certificates updated

23 October 2017 18:45:48 +0000

The *.niner.net SSL certificate was updated over the weekend on all servers, as the old one has just expired.

If you get any certificate errors in either your web browser or email program, please close down all programs, restart your computer, and try again. This should clear the cache of the programs in question and force them to download the new certificate information.

If you have any problems, please contact us.

London network restored

27 December 2015 10:17:45 +0000

The data centre informs us that connectivity on their network was restored at 09:24 UTC.

We have been able to confirm this by accessing all of our servers in this data centre:

  • Incoming mail is once again being processed immediately by server NC027, although any incoming mail sent during the disruption may be delayed a little longer until the sending mail servers try again. This is not under our control.
  • Server NC023 is also processing email immediately.

We apologise for this interruption. Denial of service attacks (especially distributed denial of service attacks) are extremely difficult and expensive to fight. We have confidence that the data centre did everything they could as quickly as they could to combat this attack.

London data centre DDoS update

27 December 2015 08:30:17 +0000

We have been updated that the denial of service attack against the London data centre is actually a large distributed denial of service (DDoS) attack, and it is still underway. Efforts are being made at multiple levels on the network to combat this attack, and we are seeing some movement of email through server NC027, although it took an hour and forty-seven minutes for a test message to get through. This indicates, as mentioned earlier, that the server is up and processing email, but that other servers (and our clients, obviously) are having problems connecting to the server.

We apologise for these problems, but this is affecting a wide range and large number of companies hosted at this data centre, not just NinerNet.

Updates will continue to be posted here as we learn more.
