Planned Maintenance Notice: CSF Firewall Update Alignment
Maintenance
Feb 20 at 11:00pm EST
We will be performing a scheduled maintenance window between February 20 and February 22 to update firewall management on select StackLinux servers.
This maintenance applies to servers in the Montreal, Canada, and Paris, France data centers that are currently using ConfigServer Security & Firewall (CSF).
What’s changing
The original CSF vendor has discontinued support and shut down its update infrastructure. To ensure continued delivery of critical security and stability fixes, CSF is now being maintained via a cPanel-managed fork. During this window, we will update affected servers so CSF is aligned with the cPanel-maintained update source.
What to expect
- No downtime is expected.
- Existing firewall rules and configurations will remain unchanged.
- No action is required.
This update is purely preventative and focused on maintaining long-term security and reliability.
If, for any reason, you prefer not to have CSF updates managed through cPanel, please contact us before the maintenance window so we can exclude your server.
This notice is shared for transparency and awareness only.
