Sites affected as of early Thursday were the main government information website ThaiGov.go.th, the ICT ministry's site at mict.go.th and the defence ministry's website, mod.go.th.
Also knocked out briefly were the websites of the state-owned TOT Plc, the firm likely to host any single gateway if it is installed, CAT Telecom and the Internal Security Operations Command. Reports also said an attack also targeted the Democrat Party website.
The last site to recover early Thursday morning was the MICT website, possibly because authorities had actually taken it offline.
