The Thai government has blocked access to its security system and the country’s main IT company, Remo, is scrambling to fix the problem, according to Reuters.
The website of the national telecommunications authority was offline Monday and the government said it was investigating whether a hack could have caused the outage.
It was not immediately clear if any data had been stolen from the site or if there were any breaches at Remo.
The outage affected thousands of people in the country, including Prime Minister Thaksin Shinawatra and his wife Yingluck Shinawaro.
In a statement, Remodel said it “does not control” the website and that it “cannot confirm the validity of this information” because it was not publicly available.
The country has been plagued by a series of high-profile corruption scandals in recent years.
In April, Yingluck and Thaksins brother, Thaksini Shinawari, were ousted in a military coup that was later ruled illegal.
Thailand’s corruption crisis has become a major concern for President Prayuth Chan-ocha as he tries to push his reforms through parliament.
The government has been criticized for failing to rein in corruption, which has helped fuel a rise in populist sentiment.
