From a friend:

There appears to have been some kind of problem at the CNN London bureau, as CNN International programming from there was interrupted tonight. At 1830 gmt Max Foster kicked off the first of the night's editions of World Business Today from London. I actually left the house to go to the store just after that. However, when I returned Jim Clancy was hosting the show from CNN Center. At 1900 gmt, rather than coming from London (with Fionnuala Sweeney or Becky Anderson), World News Europe also came from CNN Center with Colleen McEdwards, who made a point of stressing the show was coming from there.

Jim Clancy was hosting World Business Today again live from CNN Center between 1930 and 2030 gmt.
