Data center migration - services intermittently unavailable

Because of a migration of a significant part of SNTs servers to a different data center, our services will intermittently be unavailable throughout the entire day. This (indirectly) affects almost all internal and external services. This includes our mirrors, IRC servers, mail relay, GitLab CI runners, and Matrix(-related services).

There is no expected downtime for vColo, and websites hosted by SNT in general. An exception to this is the Hornet application itself. This means that, as Hornet will have limited availability throughout the day, you might not be able to log into the administration panel for your websites/domains hosted by SNT. We apologize for the inconvenience.

Past Incidents

2026-05-15

cPanel SSH and terminal access restricted on cPanel and home.snt

-- TL;DR; Because of a Linux kernel vulnerability that got discovered, SNT had to restrict ssh access for all customers and almost all active members. You can track this issue here. --

A new Linux kernel 0-day had just been released (https://github.com/0xdeadbeefnetwork/ssh-keysign-pwn/). There are no patches available as of writing in any distro of Linux or any kernel version. This meant that SNT had to restrict the Terminal/SSH access feature in cPanel and WHM as a safety measure. We will reenable this feature as soon as it seems safe to us to do so again.

We are closely monitoring the development of this 0-day and will notify you as soon as we know more here.

All websites and other services hosted by SNT will continue to function normally and securely. It does not seem that this 0-day has been exploited yet.

  • After completing the maintenance and monitoring the situation closely, we decided that it is safe again to enable the terminal feature in cPanel. This means that all services are restored to normal functionality. No data seems to have been lost or compromised.

  • Hornet, Pydio, and home.snt all received security patches as well. Therefore, Pydio and Hornet will also take part in the maintenance window scheduled tonight. I apologize for the inconvenience. We will monitor whether it is safe to turn terminal functionality back on in cPanel after the maintenance. You can find updates about this here.

    The home.snt machine got rebooted as well, so active members may make use of that machine again.

  • cPanel received security patches, and will have short security maintenance today at 11:00 PM (Europe/Amsterdam). Afterwards, the SSH feature will be enabled if we think it is secure to do so.

    cPanel cPanel limited availability

    Because of an ongoing security vulnerability mitigation, cPanel has limited to no availability of components like webmail, admin, etc, as certain components of cPanel are currently disabled. We are monitoring updates from the cPanel security team closely and will post updates once services will become available again.

    Websites hosted by cPanel are not affected in availability and should continue to work securely.

  • All systems are operational and function as normal again. No data seems to have been lost.

  • Fixes have been implemented, continuing to monitor while services recover.

  • cPanel just released a patch, we are implementing the fix and are going to monitor the services afterwards.

    • 2026-04-06

    cPanel cPanel sites unresponsive

    Due to an error in our cloud platform, almost all websites hosted by SNT on cPanel were unresponsive or not reachable for a short period of time.

    No data seems to have been lost.

  • All services have been restored and continue to function normally.

    • 2025-12-16

    Cloud vColo platform outage

    A disk replacement caused a partial outage of our cloud platform

  • The disk issue has been resolved with no data loss.

    • 2025-10-08

    cPanel cPanel disk upgrade

    We are upgrading the disk of our cPanel server. Downtime and/or performance issues for at least half an hour are expected.

    2025-08-24

    cPanel Hornet & cPanel platform outage

    An issue with the machine running Hornet and cPanel is causing a major outage of both platforms and their hosted services.

  • The machine and all associated services are working again.

    • 2025-08-02

    Admin interface Outage Hornet, Pydio and Matrix Services

    Due to a database issue, authentication is currently unavailable for the Hornet admin interface and pydio. No data loss is expected.

    All websites should still be accessible.

  • The database server has been fixed and all dependent services should function normally.
