We will be rebooting server NC041 (the primary web server) very shortly following some updates. It will be down for fewer than 60 seconds, and we’ll post here to confirm it is up again. This does not affect email at all.

At the end of August we heard from Cloudmark that, “Due to the IP [of server NC036] being located in the Netherlands, it was automatically put into a lower sending class. The sending class has been increased so deliverability will improve.” Since that time it appears that emails to shaw.ca and a few other domains using Cloudmark have been delivered without delay.
If this situation continues, it’s yet another example of what can be achieved if Internet companies work together, rather than ignoring each other.
The emergency maintenance on server NC036 earlier today was to add additional disk space for email storage. Normally this maintenance is scheduled in advance, but today a number of factors combined to require us to take action immediately. We will work to avoid this situation in the future, but the cause of the situation was one of the aforementioned factors.
Thank-you for your patience. If you have any questions or concerns, please contact NinerNet support. Thank-you.
Server NC036 is back online. It was down for 6 minutes between 02:31 and 02:37 UTC. We’ll be posting additional information about this shortly.
Server NC036 (our primary mail server) will be undergoing emergency maintenance within the next few minutes. The server will be down for approximately half an hour.
We will post an update when we are done.
Server NC041, the primary web server, experienced connectivity issues between 16:04 and 16:13 earlier today, 28 July, for those 9 minutes. The server was up, but the data centre and our external monitoring service reported a lack of connectivity during that time.
The data centre now reports that it has resolved the issue, and no more issues have been experienced since.
We apologise for this gap in connectivity. If you have any questions or concerns, please contact NinerNet support. Thank-you.
Shaw Communications Inc. and their mail filtering sub-contractor (Cloudfilter/Cloudmark) are again delaying, and now even bouncing, email sent to shaw.ca addresses. However, we have no way of communicating with Shaw mail server admins, so we cannot talk to them about how their filtering practices are non-standard and unpredictable.
Our mail server is still/again not in any of the 250 major blacklists that we monitor, so it is unclear why Shaw/Cloudfilter are causing this problem. If you are a Shaw customer, we strongly recommend that you contact Shaw and complain. We also recommend that you do not forward your email to any addresses on their domain.
Update, 2021-07-13 15:45 (PDT): Bounce messages will contain this line, or something very similar to it:
host shw-central.mx.a.cloudfilter.net[3.96.81.40] refused to talk to me: 421 shw-ibgw-4001a.ext.cloudfilter.net cmsmtp too many sessions from 178.62.195.26 AUP#CNCT
Normally bounce messages can be easily deciphered, but even we don’t know what this means or how it makes any sense.
We continued last weekend’s maintenance this weekend, and as a result the latest iterations of PHP versions 7.3, 7.4 and 8.0 have been installed on server NC041. This means that you can log into your account in the server’s control panel to upgrade your version of PHP to the version of your choice. We do recommend that you upgrade to the latest version (8.0.7), but it’s possible that your web application may have different requirements. If you have trouble with PHP 8, we suggest downgrading incrementally until you’re running a version that works for you. If you can’t run 8.0, you’re welcome to contact us if you think the issue is on our server, but generally you will need to contact the provider of the web application.
To effect the upgrade for a single website, please follow these instructions:
If you have any issues successfully carrying this out, please contact NinerNet support, and we will assist.
Thank-you.
The primary web server (NC041) is back online with a back-up copy of the corrupted configuration file. We will be analysing the cause of the problem so that we can complete this maintenance later. The server and all websites on it were down between 22:11 and 01:45 UTC. We apologise for this, and will be making adjustments for all web-hosting accounts on your next invoice.
We will not reintroduce a new configuration file until it has been tested first. A bug report has been filed with the control panel vendor.
We apologise sincerely for the down time. If you have any questions or concerns, please contact NinerNet support.
We are in the process of restoring a back-up. Once that is done we will assess what needs to be done to manually re-create the corrupted configuration file.
