WorldCom Files Chapter 11 - On A Sunday?

You've no doubt already heard or read that WorldCom, Inc. has filed what is widely being reported as the largest bankruptcy proceeding in U.S. history. See, e.g., MSNBC. My father called up wondering how they pulled it off on a Sunday. Seems the digital era knows no weekends: the U.S. Bankruptcy Court, Southern District of New York accepts filings via the ECF/PACER system, which lets registered attorneys file court documents 24/7. More about ECF (Electronic Case Files) is here, from the Administrative Office of the U.S. Courts, and here is a comprehensive list of courts which have implemented or are implementing the system. (Sadly, these factoids will do nothing to prop up the morning's markets; see news.com.au.)
