Unfortunately, until just now there was a problem with our Ceph storage cluster, which affected some vServers and root servers. This was caused by a problem with one of the Ceph nodes, which had an impact on the entire cluster. We are investigating this problem further and ensuring that it cannot happen again in the future.
We apologise to all affected customers for any inconvenience and offer a free 4-day runtime credit. Please contact our support for this.
