Resolved Date:14 May 2019 22:30 SAST
Notice ID: #3782
Start: 14 May 2019 21:00 SAST
Maintenance Window:9hours
Issue:Replace faulty power supply card on one of the B-feed UPS systems
Attending: Hetzner Engineers
Additional Information:The power card on one of the B-feed UPS systems will be replaced to resolve an erratic fault condition on the UPS and to restore full power redundancy to both power feeds.

All power feeds will remain live for the duration of the maintenance window.

Precaution is being taken to ensure there is no impact on the critical power feed, however, the maintenance will require switching between the A and B power feeds and the synchronisation of UPS systems. Colocation customers are reminded to ensure their equipment is connected to both A and B power strips inside the rack to mitigate the risk of a power outage on one of the power feeds.

Webhosting and Truserv hosting equipment is already protected by both feeds and requires no further action.
