GitLab

Aufgrund einer Störung des s3 Storage, könnten in nächster Zeit folgende GitLab Funktionen nicht zur Verfügung stehen: LFS, Container Registry, Job Artifacs, Uploads (Wiki, Bilder, Projekt-Exporte). Wir bitten um Verständnis. Es wird mit Hochdruck an der Behebung des Problems gearbeitet. Weitere Informationen zur Störung des Object Storage finden Sie hier: https://maintenance.itc.rwth-aachen.de/ticket/status/messages/59-object-storage-pilot
