    Bollob\'{a}s and Thomason (1985) proved that for each k=k(n)∈[1,nβˆ’1]k=k(n) \in [1, n-1], with high probability, the random graph process, where edges are added to vertex set V=[n]V=[n] uniformly at random one after another, is such that the stopping time of having minimal degree kk is equal to the stopping time of becoming kk-(vertex-)connected. We extend this result to the dd-uniform random hypergraph process, where kk and dd are fixed. Consequently, for m=nd(ln⁑n+(kβˆ’1)ln⁑ln⁑n+c)m=\frac{n}{d}(\ln n +(k-1)\ln \ln n +c) and p=(dβˆ’1)!ln⁑n+(kβˆ’1)ln⁑ln⁑n+cndβˆ’1p=(d-1)! \frac{\ln n + (k-1) \ln \ln n +c}{n^{d-1}}, the probability that the random hypergraph models Hd(n,m)H_d(n, m) and Hd(n,p)H_d(n, p) are kk-connected tends to eβˆ’eβˆ’c/(kβˆ’1)!.e^{-e^{-c}/(k-1)!}.Comment: 16 pages, minor revisions from first draf
