It’s the old cliche, but County’s season won’t be defined by results against Celtic and Rangers. Instead, they must look at their own performance.
Don Cowie's side made it stuffy and uncomfortable for Celtic, who until they made changes, failed to carve them open or even remotely test goalkeeper Ross Laidlaw.
The County midfield didn't allow their visitors to find their usual rhythm and Connor Randall and Elijah Campbell impressed in cutting out any danger.
In second half, when you'd expect Celtic to throw all their might, muscle and money at it, Jordan White worked tirelessly to act as an out for the hard-working defence and midfield.
Which is why the winner will hurt County so dearly. Down at their corner flag, Celtic recovered possession and made their way up the park in an instant.
County have now lost seven points from winning positions this season, more than any other Premiership side. That is something they must address.
But it was an afternoon were Cowie's side made Dingwall almost as daunting as Dortmund for Celtic, and there's plenty to take from that.
