Thank you. I was watching until first stage separation and then turned it off, only to read later that it failed.

Looks like the second stage “simply” didn’t ignite? Assuming they got a clean staging event with no damage (eg. stuck/hung clamps) then all eyes are on the 2nd stage for failure to light off. Hopefully they have enough telemetry to point to what went wrong. Otherwise you’re in the educated guessing game of what could have gone wrong with what percentage chance...
