YouTube blocked in Thailand

This is really charming! YouTube is being blocked here in Thailand. I accessed it okay yesterday but today all that comes up is the following message:

Sorry, The web site you are accessing has been blocked by the requested of The Communication Authority of Thailand. For more information please contact: Ministry of Information an Communication Technology Building 9, TOT PCL Chaeng Wattana Rd. Laksi Bangkok 10210 Tel. 0-2505-7147,0-2568-2498
It's in both English and Thai. It makes me wonder what, if anything has been uploaded that has offended whomever. So much for freedom of speech!
