Matomo: Changes to Multi-Server Setups

To improve stability and maintainability of larger Dedicated Matomo installations, we will perform some planned changes to the configuration.

Why this change?

Operating Matomo in a multi-server setup contains some complexity. We will further standardize and optimize the structure of the single parts of the stack, the monitoring and our automation. This will ensure we can further improve stability and performance, while reducing operational overhead and improving maintainability.

Which installations are affected?

These planned changes affect larger Dedicated Matomo installations that we operate on multiple servers. We will perform the planned changes one installation after the other during this 2-day maintenance window.

What does this mean?

  • Tracking of website users will continue without interruption, no tracking-data will be lost.
  • Access to the Matomo GUI for accessing the statistics will be interrupted temporarily for a short period of approx. 30-60 minutes per installation.
  • After the Matomo GUI is accessible again, tracking-data of the current day will show up with a slight delay until the queued tracking-data backlog is processed (duration of this process depends on the amount of tracking-data to be processed from the queue).

You don't have to do or change anything regarding this change.

If you have any questions, do not hesitate to contact us.

Mailcow: Changes to Email Alias Forwarding

To improve email deliverability, we will restrict email aliases from forwarding messages to external domains.

Why this change?

Forwarding emails to external providers can cause authentication issues (particularly SPF), resulting in messages being rejected or classified as spam.

What does this mean?

  • Existing aliases will continue to work as usual, unless modified.
  • Forwarding to locally hosted domains remains unaffected.
  • Creating or modifying aliases to forward to external domains will be restricted.
  • External forwarding will remain possible through an alternative method.

For instructions, please see our forwarding guide.

If you have any questions, do not hesitate to contact us.

Managed Server 8/9/10: Dirty Frag Kernel Vulnerability

The Dirty Frag vulnerability can obtain root privileges on major Linux distributions by chaining the xfrm-ESP Page-Cache Write vulnerability and the RxRPC Page-Cache Write vulnerability.

  • As of now, patched kernel versions are not released yet
  • To mitigate this issue at this time, we implemented a workaround on the affected systems

We will test and install the required patches as soon as they're released by Debian. We will announce this as usual as soon as the update is ready.
