This website is temporarily unavailable

We have temporarily taken the website offline as a precautionary security measure.

Critical security vulnerabilities have been announced for PHP, a software platform used by many websites. Under certain circumstances, these vulnerabilities could allow attackers to execute malicious commands on a server. To protect systems and data as effectively as possible, we have temporarily restricted access to this website.

Official BSI Security Advisory

On October 21, 2026, the German Federal Office for Information Security (BSI) issued an advisory about critical security vulnerabilities in PHP. The advisory describes potential risks to web applications and recommends prompt protective measures. We take this situation seriously and have restricted access as a precaution to reduce potential risks to our systems and data.

What does this mean for you?

Taking the website offline is a preventive protective measure. It does not automatically mean that this website has been attacked or that any data has been affected. We are reviewing the situation and taking the necessary steps before restoring the service.

We are working hard to resolve the issue

Our team is assessing the impact and preparing the necessary security measures. Our goal is to make the website available again as soon as possible, without introducing unnecessary risks.

We partly depend on external updates

To resolve the issue securely, we need appropriate, verified security updates from the responsible software maintainers and other parties involved. We do not have complete control over when these updates are released. As soon as the required updates are available and suitable for our systems, we will implement the next steps as quickly as possible.

Our goal: security and availability

We will restore access to the website as soon as our assessment determines that it is safe to do so. Thank you for your patience and understanding.
