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: 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.

NC036: Mail server blocked by Microsoft

14 December 2018 05:33:38 +0000

We are aware that the IP address of server NC036 (the primary mail server) has again been blocked by Microsoft’s various mail services, variously known as Outlook.com, MSN, Hotmail, Live.com, etc.

Although we are a member of their Smart Network Data Services programme and Junk Mail Reporting Program, which are supposed to allow us to proactively prevent these kinds of issues, we have been unable to use the service as advertised, or at least as we understand it’s supposed to work. We will continue to attempt to have this server’s IP address removed from their blacklist, and report here when we have success.

In the meantime, outgoing mail to their primary domains (hotmail.ca, hotmail.com, hotmail.co.uk, live.com, msn.com and outlook.com) is being routed through our relay server. If you receive a bounce message that reads similarly the one below to an email you’ve sent, it is probably for a private domain hosted by Microsoft of which we are not aware. Please contact us and we will add it to the list of domains for which email is routed through our relay server:

host 901e3cd0af6f44ab11b5a5e8a49da3.pamx1.hotmail.com[104.47.0.33] said: 550
5.7.1 Unfortunately, messages from [178.62.195.26] weren’t sent. Please
contact your Internet service provider since part of their network is on
our block list (S3140). You can also refer your provider to
http://mail.live.com/mail/troubleshooting.aspx#errors.
[HE1EUR01FT033.eop-EUR01.prod.protection.outlook.com] (in reply to MAIL
FROM command)

Please remember that all email you send through our mail server must be to recipients with whom you already have a business or personal relationship, and all mass email must be explicitly requested — i.e., Confirmed opt-in (COI) or Double opt-in (DOI) email.

Thanks for your cooperation, and our apologies for this inconvenience.
