The first websites went offline at about 10pm Wednesday, after the "Anti-CAT Tower Mob" group called on its 127,000-plus Facebook fans to attack, even amid threats from the government that such actions would be treated as violations of the Computer Crime Act.
The ICT deputy permanent secretary, Somsak Khaosuwan, claimed Wednesday night his ministry's site did not crash because of an attack, but because it was overloaded by visitors monitoring the planned attack.
