Dear customers,

Unfortunately, some customer systems are still affected.

We deeply regret this and are in close contact with the data center to restore your services as quickly as possible.

We have just received the following update from Frankfurt:

Dear customers,

During the announced maintenance work, an unexpected power outage occurred today in our data center rooms R1 and R2 at the FRA1 location. In order to be able to carry out the announced maintenance work on the UPS, additional protective measures have been taken to further safeguard against any impact on customer infrastructures.

During the initiation of maintenance measures, the active systems were diverted to redundant systems. During the switchover and initiation of parallel feed-in, a short circuit occurred between two phases, triggered by a technical defect. The short circuit caused the relevant fuses to trip properly.

The emergency process was initiated immediately, and an initial fault analysis was conducted. The fault was quickly identified, and power restoration was initiated immediately. Due to this incident, all further maintenance work was halted.

We deeply regret the disruption and will address it internally and make appropriate improvements. Thank you for your understanding.

We received the following additional feedback from the data center:

Power has been restored. Our systems are back up and will be fully operational shortly.

The systems of Quality Location and its customers are partially active again.

We ask for your patience until all systems are fully available.

Dear customers,

The following feedback was received from the data center team.
