We consider the SO(d)-equivariant Yang-Mills heat flow \(\begin{aligned} \partial _t u-\partial _r^2 u-\frac{(d-3)}{r}\partial _r u+\frac{(d-2)}{r^2}u(1-u)(2-u)=0 \end{aligned}\) in dimensions \(d>10.\) We construct a family of \({\mathcal {C}}^{\infty }\) solutions which blow up in finite time via concentration of a universal profile \(\begin{aligned} u(t,r)\sim Q\left( \frac{r}{\lambda (t)}\right) , \end{aligned}\) where Q is a stationary state of the equation and the blow-up rates are quantized by \(\begin{aligned} & \lambda (t)\sim c_{u}(T-t)^{\frac{l}{\gamma }},\,\,\,l\,\,\,\text {is any positive integer},\\ & \gamma =\gamma (d)=\frac{d-4-\sqrt{(d-6)^2-12}}{2}. \end{aligned}\) Moreover, such solutions are in fact \((l-1)\) -codimension stable under pertubation of the initial data.
