Zulu5 is temporarily offline.

A critical security vulnerability in PHP, a core component of our platform, was made public before the official patch (see the CERT-EU security advisory 2026-018). This affects PHP installations worldwide, not only Zulu5. As a precaution we have taken the platform offline until the patch is available and deployed. We expect to be back online today, 21 October, in the evening (CET). We will update this page as soon as we are back. Sorry for the inconvenience.
