The third stage was meant to get to the east Pacific off Chile. The underspeed means that won't happen - beon the lookout for reentry reports in Borneo or New Guinea.

It's a fairly reflective (given that it's all white, and big) thing, no?
The ISRO chairman announced on podium that due to heat shield seperation failure , mission unsuccessful on DD national tv.
Like Sea Launch.... if it fails, kill the webcast.

With a 167 km perigee, won't this fall from orbit fairly soon? - Ed Kyle

It's a bit embarrassing that the announcer kept repeating that performance was normal/nominal even though we could see that the altitude and velocity graphs were diverging from their expected plots. It seemed like he was reading off a script rather than examining the data. And especially given that they should have known by that point (minutes before) that the fairing failed to separate.

That was the RCO (Range Control Officer).Acting as per the instructions of the ISRO Chairman of course.
The failure is of the rocket and the satellite built by the private consortium remains untested, scientists said.
