We are still monitoring the situation as parts of the system continue to behave strange.
The storage updates have been deployed and all systems seem to have stabilized. We are monitoring the situation bevor returning back to normal operations.
We were able to pinpoint a potential issue. After the core systems maintenance last thursday no schema version upgrade to the underlying storage pool was applied, which caused I/O problems, high load and drive fragmentation. These are potentially valid causes for the current outages.
After applying the storage upgrade on parts of the core systems, partial network recovery was observed.
We are still monitoring the situation and will keep you updated. We will continue the upgrades, if the systems stabilize further.
The root cause of this issue is still not found.
We are still experiencing regular partial network outages.
We are currently experiencing an unexpected outage with our DHCP service. As a result, the automatic assignment of IPv4 addresses is failing across the network.
Due to currently unknown reasons, we have synchronisation problems between our core database masters, which could lead to network outages or other service disruptions.
We are currently working hard on resolving this issue.
In this timeframe we conduct important maintenance work on parts of our core virtualization infrastructure. This should not impact broad network and service operation. Some specific services may have some downtime.
