Morning investigation followed by restoration report
At 09:24 SAST on 16 October, corresponding to 07:24 UTC, City Power published a notice about a suspected interruption affecting Doornfontein and New Doornfontein from Siemert Substation. Operators were investigating. That notice establishes when the problem was reported by the operator; it does not provide a verified time at which electricity first went off.
The subsequent statement was published at 16:47 SAST, or 14:47 UTC. City Power explicitly linked its restoration update to the outage reported that morning and attributed the interruption to a faulty cable. It said supply to customers in Doornfontein and New Doornfontein was fully restored. Both notices come from the same operator, rather than independent sources.

What the restoration statement covers
The restoration report applies to this Siemert incident and the two areas named by City Power. It does not establish citywide restoration across Johannesburg or resolve separate Central CBD and older Siemert records. No affected-customer total or complete address boundary is available in the checked evidence, and individual customer exceptions have not been independently audited.
The actual restoration switching time remains unknown. The later post confirms the operator’s reported outcome by its publication time, without establishing the precise moment electricity returned. An outage duration is therefore not calculated from the two posting times. The latest supported status is City Power’s full-restoration statement for this named incident.
Preparing for another interruption
The runtime calculator helps compare essential devices with available battery capacity. The internet backup planner supports planning for router and connectivity needs. These tools help with preparation; they do not verify whether an individual property has electricity or diagnose a remaining local fault.
