Google executive vows vigilance

Geneva: Google´s vice president Vint Cerf voiced concern Thursday about a US move to roll back "net neutrality" rules for internet access, and vowed to be on the lookout for any "serious side effects".

Cerf, considered one of the fathers of the internet, also said he believed that the decision to overturn the rules requiring internet providers to treat all traffic equally was not the last word in the matter.

Several lawsuits are expected to try to block the change, and a political shift in Washington could also lead to a reinstatement of the rules, Cerf told journalists on the sidelines of an annual conference on internet governance in Geneva.
