NC036: Post-mortem

21 September 2020 08:42:47 +0000

As noted in the previous two posts, there was a virus outbreak on server NC036 (the primary mail server) this morning. Apparently the machines associated with five email accounts on three domains were compromised, allowing criminals to use those accounts to send thousands of viruses. These were intercepted by our anti-virus scanner, but due to the volume of activity on the server we had to shut down the SMTP side of the mail server while we determined which email accounts were compromised, suspended them and removed their messages from the mail queue.

Please note that what happens in almost all cases when email accounts are compromised is that the computer (or one of the machines or devices on which those accounts are configured) is what is actually compromised; it is not the server. The account owner’s machine is usually infected with a virus or other malware, and the account’s password is then transmitted to the criminals behind the virus. They then launch an attack via the legitimate and correct password. It’s as if your car was stolen and the thief used it to commit a crime; the car behaved as it was told by the guy with the key, but is not responsible for the crime. On the other hand, the owner of the car may have left the key in their car and the door unlocked, contributing to the compromise. This is why it is vitally important that you have anti-virus software installed on your computer, and kept up-to-date.

If you have any questions about this, please feel free to contact NinerNet support, and we’ll be happy to answer your questions or concerns. Our apologies for the interruption.

NC036: Mail server is back online

21 September 2020 07:26:54 +0000

Our apologies. The sending side of the mail server (NC036) is back up. It was down for 21 minutes between 06:56 and 07:17 UTC. The ability to check your email account was not down.

We will post additional information and contact the affected clients shortly.

NC036: Mail server paused while we clean up a spam outbreak

21 September 2020 07:05:48 +0000

Server NC036 (the primary mail server) is temporarily paused while we clean up a huge virus outbreak. I will be back online as soon as possible.

Phone system down

4 June 2020 04:31:52 +0000

Clients should be aware that our North American phone system is down right now, and has been since shortly after 17:00 Pacific time today, 3 June (00:00 UTC on 4 June). Currently we have no estimate from our phone provider when this issue will be rectified.

However, of course, email is our primary method of communication and providing support, so please continue to use that. It’s working just fine.


Update: The phone system was down for about five hours due to a data centre issue during maintenance.

NC041: Automated certificate renewals should be working again

12 January 2020 13:01:11 +0000

The issue with automated renewals of Let’s Encrypt certificates on server NC041 should now be fixed. We have taken the action suggested by the control panel vendor, and we are waiting for the first automated renewal to occur to see if everything is once again working. If, as we expect, the issue is fixed there will be no further posts on this subject.

If you receive any error messages related to certificate renewals — or any error emails at all — please contact NinerNet support and we’ll investigate further. Thank-you.

NC041: Automated renewals of Let’s Encrypt certificates failing

10 January 2020 03:21:00 +0000

Since about 1 January automated renewals of Let’s Encrypt SSL certificates have been failing on server NC041, and as a result you may receive automated emails from server NC041 that look like this:

Subject: Let’s Encrypt certificate renewal failed!

An error occurred requesting a new certificate for example.com, www.example.com from Let’s Encrypt : Web-based validation failed : <pre>sh: certonly: command not found
</pre>

We currently have a support ticket open with the control panel vendor to find out why this has suddenly started.

Since the renewal of Let’s Encrypt certificates is automatically scheduled to happen one month before they expire, the existing certificates will continue to be used and remain valid and in force. The issue will be resolved before these certificates start expiring in February.

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

NC033: Incident with primary nameserver resolved

15 November 2019 03:10:35 +0000

Following an operating system update that was applied at 00:37 UTC on 15 November the primary nameserver failed to restart. This was noticed immediately upon completion of the update, and we started troubleshooting.

After extensive research on the likely cause and resolution of the problem we determined that the quickest way to get the nameserver back online was to roll back the update and restore from a back-up. There were some issues with this, however, that necessitated implementing a back-up plan for company email in order for us to gain access to our account at the data centre where the nameserver is hosted. Once this was accomplished the restore was initiated.

The nameserver was back online at 02:28 UTC.

During the time the server was down domain information would have been cached by DNS resolvers that already had a cached copy of the DNS information for your domain. However, it is possible that some incoming email may have been delayed or possibly bounced, or people trying to browse your website would not have been able to see it. For this we apologise.

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

Mail server latency issue resolved

30 September 2019 23:25:22 +0000

This issue on server NC036 appears to have been resolved, although we are awaiting official confirmation from the data centre. Should there be no change of status this issue will be closed with no further update here.

As always though, if you have any issues or concerns please contact support. Thank-you for your patience.

Email server (NC036) latency issue

30 September 2019 22:28:56 +0000

We are aware that connections to the primary mail server (NC036) are slow to the point they are timing out. We are told by the data centre where this server is located that this is an infrastructure issue of which they are aware and on which they are actively working.

We apologise for this temporary inconvenience. We will post further updates here as necessary or when the issue has been resolved. In the meantime, if you have any questions or concerns, please contact support. Thank-you.

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.
