The Las Vegas Monorail passes by MGM Grand, April, 27, 2006, in Las Vegas.

The online room booking reservation system at MGM Resorts International is again functioning after nearly two weeks of being disabled in response to a crippling cybersecurity attack, officials said in a Friday evening social media post.

MGM, with 28 properties worldwide, including many up and down the Las Vegas Strip, was targeted in a cyberattack on Sept. 10. 

The nature of the issue was not detailed, but a statement from MGM said efforts to protect data included “shutting down certain systems.” The FBI is taking part in the investigation.

The shutdown prevented credit card transactions and crashed the BetMGM sports betting mobile app and company websites. It also prevented digital access to guest rooms and halted some slot machine play.

Systems slowly started to return to normal this week. The company said Wednesday that its casino and hotel services are “operating normally,” although online room booking at mgmresorts.com remained shuttered.

That’s now been fixed.
