Time: June 26th, 2017, since 5:30 p.m.
Affected: P drive, HPC
Impact: no access
On Sunday, June 25th of 2017, there was an approx. 10-minute power failure between 5:30 p.m. and 6:00 p.m. at the GWDG data center on the Max Planck campus (Faßberg location) as well as at the redundancy location in the telecommunication center of the university caused by problems of the local power grid operator. Possibly the second GWDG redundancy location in the state and university library was also affected.
UPS systems strongly reduced any harm. Unfortunately, the UPS did not supply the mass storage systems long enough, so that the file service failed.
In the meantime, the file service is largely available again. Not yet available are the Windows login profiles and P drives of the university as well as the group drive of the economic and social sciences. Since one storage system fails with a hardware defect, unfortunately no statement can be made about the time of the restart.
All HPC nodes had failed due to the power failure and will be available again at approximately 11:30 a.m.
