Our image server received a critical BIOS update and needs to be restarted urgently. The colleagues at digiS will do so starting at 2:30 p.m. The domain asset.museum-digital.org, from which images are commonly served in the frontend of museum-digital is therefore now available for now.
We were fortunately notified early enough to mitigate the issue in instances of the public “frontend” (e.g. nat.museum-digital.de; bu.hu.museum-digital.org) by serving images from a fallback location.
