Cydna power outage: City Power investigating in Atholl, Illovo and Inanda

City Power has confirmed an unplanned electricity interruption affecting customers in Atholl, Illovo and Inanda. Its Cydna notice on 15 October says operators are investigating on site. The statement identifies an interruption in the named areas, but does not provide an affected customer total, a cause or a restoration estimate.

Status of this incident

Current status unconfirmed

Last known status: confirmed by the source · 15 October, 12:31 SAST: City Power confirms the Cydna interruption; cause, customer total and restoration estimate unknown. Source checked 15 October, 13:27 SAST.

Source moment: 15 Oct 2026, 10:31 UTC (12:31 local time)

In 20 seconds

  1. City Power confirms an unplanned Cydna interruption affecting customers in the three named areas.

  2. Operators are investigating on site; a cause and restoration estimate remain unknown.

  3. The notice does not establish a loss of electricity at every address in the named neighbourhoods.

What City Power has confirmed

The operator published its update at 12:31 SAST on 15 October. That is the time of the statement, rather than a verified start time for the electricity loss. The available evidence does not establish exactly when the interruption began, so a precise duration cannot be calculated from this update.

Atholl, Illovo and Inanda are the areas named in the notice. The confirmed impact is on customers in those areas. No connection list or customer count is supplied, and the notice does not establish that every household or business in any one neighbourhood lost power. No citywide total can be inferred.

Investigation and the remaining unknowns

Operators investigating on site is the reported stage of the response. It does not establish that a fault has been located, that repairs have started or that supply has returned. The cause and the time needed for restoration remain unknown in this operator statement. No completion deadline has been given.

Earlier Cydna incidents were reported restored by 11 October. A technical link between those events and this 15 October interruption has not been established. This update is therefore treated separately: the earlier events do not supply a start time, cause or duration for the newly reported loss. A later operator explanation could clarify that relationship.

Planning around an uncertain interruption

For essential electricity planning, the runtime calculator compares device demand with battery capacity. The internet backup planner helps assess connectivity needs. These tools support preparation; they do not check a local connection, identify the network fault or predict when City Power will complete its work.
