The company has reached out to the organization that manages the domain name to resolve the issue, MYNIC, a Google Malaysia spokesperson said in a statement.
MYNIC is operated by the country's ministry of communications and multimedia, and is the administrator for all websites ending with ".my", according to the company's website.
The website for Malaysia Airlines experienced a similar problem in January, but the airline quickly reassured users that their bookings and private data had not been compromised.

Earlier, the website of Malaysia Airlines was commandeered for several hours by hackers who referenced the Islamic State jihadists and threatened to expose data taken from the carrier's servers.

The attack, whose motivation remained unclear, was claimed by the "Lizard Squad", a group that has taken credit previously for denial-of-service attacks around the world.
It was not clear why the troubled airline was targeted, but the Lizard Squad said on its Twitter feed that it was "Going to dump some loot found on servers soon."
Visitors to the website were re-directed to another page bearing an image of a tuxedo-wearing lizard and reading "Hacked by LIZARD SQUAD - OFFICIAL CYBER CALIPHATE".
It also carried the headline "404 - Plane Not Found", an apparent reference to the airlines' puzzling loss of flight MH370 last year with 239 people aboard which tipped the already struggling carrier into crisis.
