On 30 November 2013, during the mass protests going on in Bangkok, a group of unidentified protesters infiltrated CAT Telecom headquarter, with hosted its data center, to cut off its electricity. This affected roughly 92,000 clients of the company, both public and private. This resulted in about 300 million baht ($10 million) in lost transactions. As upon the system shut down, internet was inaccessible, phone lines were down, and ATMs were out of service.[8]

The junta also cancelled the Thaksin government's telecom excise tax policy. The Thaksin government imposed an excise tax on private fixed and cellular services, and then allowed telecom companies to deduct the amount they paid in excise tax from concession fees to TOT and CAT Telecom. The total amount paid by the private telecom firms did not change. The Surayud government's excise tax cancellation meant that TOT and CAT Telecom would receive their full concession payments. However, TOT and CAT were then forced to increase their dividends to the Ministry of Finance to account for their increased income.[7]

The junta also appointed General Saprang Kalayanamitr as the new chairman of the board of directors for both CAT Telecom and TOT. Saprang was accused by the founders of People's Television (PTV), a new satellite television station, of being behind CAT Telecom's refusal to grant an internet link from Bangkok to a satellite up-link station in Hong Kong. PTV was established by several ex-executives of the Thai Rak Thai party. CAT Telecom, however, claimed that it never received PTV's application for internet access.[6]
