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.
