We performed a controlled shutdown of the secondary name server ns2 due to a detected inconsistency in replicated DNS zones.
We are currently investigating why axfr zone transfer is not working as expected.
All dns zones are still resolveable through the primary nameserver ns1.
We have redeployed the secondary name server.
All DNS zones are now available and consistent on both nameservers.

The provider of the subnet 18.104.22.168/24 has interrupted the routes.
I have assigned a new IP address to the affected servers. If the server is not accessible via this address after a reboot, the address may have to be adjusted manually using the noVNC console.
All customers have been migrated to other IP-Address spaces.

Backup serverProxmox backup server peformance issues
Current migration of data between raid arrays on the backup server provided by our housing provider is causing performance issues that result in the inability to create or restore backups at this time.
After the data migration is complete, the backup creation and restoration tasks are performed much faster than before.
The backup server is fully operational.
The Backupserver is now beeing migrated back to a raid 10 array.
The migration has finished successfully.

CEPH clusterPerformance issues due to maintenance
Performance issues detected
Migration of data has finished successfully. Everything is up and running again.
We have temporarily added a new object store daemon to ph24-8 and managed to get the crashed ph24-8/9 object store daemon working again.
The ph24-5 hypervisor was successfully taken out of service.
Migration of data that is still in progress may affect the performance of the Ceph cluster.
The ph24-8/9 object store daemon crashed while we were performing a data migration to other object stores.
This failure resulted in unavailability of 25 pg's. The data was not lost, but was unavailable for a few minutes.

NetworkNetwork unavailable for subnet 22.214.171.124/24
All services from the network 126.96.36.199/24 are unreachable
The owner of the IPv4 resources 188.8.131.52/24 removed the route object for the subnet because of an abuse report regarding fraudulent content being hosted at web.prohosting24.de.
The fraudulent content has been removed and the connectivity was restored by recreating the old route object.
