Over the next several weeks are are going to try to get all of our systems updated to Debian 9 (oldstable) or ideally Debian 10 (stable) wherever possible. Many systems are still running Debian 8 LTS for which security support ends in June.
We will do our best to minimize disruptions. Any work that’s unavoidably disruptive will be performed during our weekly maintenance window every Saturday between 10:00 and 22:00. An example of a system that’s disruptive would be the account control center, webmail, or IMAP/POP3 hosted mail. To completely update a system there are required reboots, and in some cases (most notably IMAP/POP3 hosted mail), forced switches between active/standby pairs to verify functionality. Updates on our in-office system will cause interruptions to our phone and hotline number (which run on Asterisk) while we perform its upgrades. Email us if you don’t hear the voice prompts answer since someone will be watching for emails when we know voice is being worked on. Work to non-interactive systems like ns1/ns2 may be performed at any time since our supported configuration is that customers configure both on their domain, not just one. We may also decide to migrate older hardware based systems to a virtual machine on a case-by-case basis.
If you have any questions please contact support.
