Yes. But they’ve launched over 360 and this is the first failure, so it looks like a manufacturing, not design, fault.
There is a rumour going round they suspected a problem and deliberately used it in a Starlink launch, rather than scrap it, as worth the risk.
Don't believe it, unless they didn’t think the FAA would ground them with their record to date.
Regardless, I don’t think it will be for long.
