[1] PLN expressed its apology regarding this. [8]
The blackout began at 11:50 local time, when Jakarta MRT authorities began to detect the loss of electrical supply, [9] rendering its trains inoperable and requiring people stuck inside to evacuate. Jakarta LRT and KRL Commuterline also suffered from the blackout making TransJakarta the only mass transit transportation remaining in operation at the time of the blackout. The governor of Jakarta, Anies Baswedan made TransJakarta and Jakarta MRT services free of charge until the end of the day.
In the telecommunications sector, the telephone network was also disrupted. [10] Disrupted networks included Telkomsel, [11] Indosat, XL Axiata, 3, and Smartfren. [12] Gojek and Grab had problems due to the lack of internet services.

Power to some rural and residential areas in Jakarta had not been restored past midnight. Some areas initially had electricity restored by midnight or later, only to have it cut off again. [13]
Most of the traffic lights of Jakarta stopped functioning. [14]
At least eight fires occurred on Sunday night and Monday morning in eight different locations due to the power outage. [15] This probably had happened due to the use of candles as lighting during the power outage. [15]
The blackout became viral on Twitter. [16] The hashtag #MatiLampu topped the worldwide trending topics with 8,873 tweets. Other tweeted hashtags include #MatiListrik, #ListrikPadam, and #Blackout. [17] Netizens also compared the #MatiLampu hashtag with a Ria Ricis video titled "Saya Pamit". [18]
