We update our estimates of charged and neutral current neutrino total cross sections on isoscalar nucleons at ultrahigh energies using a global (x, Q{sup 2}) fit, motivated by the Froissart bound, to the F{sub 2} (electron-proton) structure function utilizing the most recent analysis of the complete ZEUS and H1 data sets from HERA I. We compare both to our previous work, which utilized only the smaller ZEUS data set, as well as to recent results of a calculation using the ZEUS-S based global perturbative QCD parton distributions using the combined HERA I results as input. Our new results substantiate our previous conclusions, again predicting significantly smaller cross sections than those predicted by extrapolating pQCD calculations to neutrino energies above 10{sup 9} GeV.
