http://www.americantelegram.com/governmenttelegrams.htm Western Union has this on their page, but perhaps they have cut it off a few days early, because the "send now" link just takes you back to the same place:
"Effective January 31, 2006, Western Union will discontinue all Telegram and Commercial Messaging services. We regret any inconvenience this may cause you, and we thank you for your loyal patronage."
