Performance limitations over

Due to a software bug our central storage servers (Tier1: SSD based) are synchronised themselves. This is lead to performance limitations.

Since this morning 05:15 the performance limitations are over.

During the night from Sunday, the 11th of June 2017 to Monday, the 12th of June 2017 our central storage servers (Tier1: SSD based) failed at 02:40. The reason for this outage was a software bug in the storage software (GlusterFS).

Our employees reacted promptly and since 03:25 our central storage servers (Tier1: SSD based) are up and running again. The outage led to a synchronisation of all the data. This synchronisation led to very high reads and writes, which affected the performance of the virtual machines.

The data consistency was preserved at all times and therefore no data was lost!

We apologise for any inconvenience caused and hope for your understanding.

Read and writes on our storage servers.
