It appears that the current blackouts in Peninsular Malaysia are affecting rail services as well as telecommunication services. Digi has updated that they are currently experiencing network interruptions in most areas in Selangor and the Klang Valley due to the current power outage by Tenaga Nasional Berhad.

Digi didn’t elaborate on the extent of the network interruption but usually telcos should have backup power for most of its critical sites and infrastructure. At the time of writing, Digi is the only telco that has posted an update on the interruption.

Fixed broadband provider Unifi didn’t report any issues but they have tweeted a PSA by sharing the tweet from TNB.

[ UPDATE 14:56 27/07/2022 ] TM has just reported interruption for Unifi services at selected areas in the Klang Valley.

As reported earlier, several locations in Peninsular Malaysia are currently facing power outage which include major towns and cities in Penang, Pahang, Negeri Sembilan and Perak. Even KLIA, Sunway Pyramid and KLCC are reported to be affected as well. Not only does this affect consumers at home, but commercial users as well.

TNB has yet to provide an explanation on the cause of the issue. Based on some tweets, it appears that power has been restored at some locations. Lembah Pantai MP Fahmi Fadzil had tweeted that the issue is caused by a trip on the 132kV transmission grid. Are you experiencing any issues on your mobile network?
