    1. VIER available again

      We have installed the PHP update, and VIER is fully available again. There is no indication that VIER or your data were affected. Thank you for your patience today.

    2. VIER temporarily offline

      As a precaution we have taken VIER offline. A security issue has been announced in PHP, the software that many websites worldwide are built on, including VIER. CERT-EU, the cybersecurity service of the EU institutions, advises organisations to consider taking websites offline until they can install the official update. There is no indication that VIER or your data are affected. We will bring VIER back as soon as the update is installed and post here when it is. We are sorry for the inconvenience this causes.
