Speed Channel is covering it. There is a major issue with the Michelin tires. The company has apparently deemed the tires unsafe to drive on, thus disallowing the 7 Michelin teams to run the race. Michelin and 9 teams (excluding only Ferrari) asked the FIA twice to add a chicane in turn 13 to slow the speeds but were denied.
As of now I don't know what's going on!
edit: all the teams are on the starting grid, so they race should go on...
