I can watch this for the remaining 8hrs of the race.
8am start of pace lap, race resumes at 8:20. That's 2am Eastern and 11pm Pacific.
There will be at least a 90 minute warning before the Nurburgring 24 Hours goes back green, so we've got at least that. I think at least 2 or 2.5 hours. The system is moving west, and there's lots of rain upwind. Aston Martin Avia says 6am local (midnight ET, 9pm Pacific) for a restart, but nothing official.
